An object has balanced forces acting on it. Which of the following describes the result these balanced forces have on the object? A. It remains at rest or speeds up in the same direction. B. It speeds up in the same direction or moves at constant speed. C. It speeds up in the same direction or slows down. D. It remains at rest or moves at constant speed in the same direction.
Answer:
C.It remains at rest or moves at constant speed in the same direction.
Explanation:
First, remember the Newton's 1st law of motion which states that the object at rest will remain at rest and that in motion will stay in motion with the same speed and same direction unless acted by unbalance forces.
Balanced forces on an object occur when two forces at act on an object are equal in size and act in opposite direction. In this case, a stationary object will stay at rest while an object moving will continue to move at the same speed and same direction.
An object acted by balanced forces is said to be at equilibrium, thus the state of motion will be maintained.The object will not accelerate. A good example of an object acted by balanced forces is an object at rest or in constant motion such as a car that stopped at red-light signal or a car travelling at a constant speed.
What mass of sodium phosphide would be needed to react fully with 5.4x1025 formula units of
strontium oxide?
Answer:
5974 g of Na₃P
Explanation:
We determine the reaction:
2Na₃P + 3SrO → 3Na₂O + Sr₃P₂
2 moles of sodium phosphide react to 3 moles of strontium oxide to produce 3 moles of sodium oxide and 1 mol of strontium phosphide.
We know that 1 mol of anything contains 6.02×10²³ formula units, so:
5.4×10²⁵ formula units . 1 mol/6.02×10²³ formula units = 89.7 moles
This is the amount we have, initially for SrO.
Ratio is 3:2. 3 moles of SrO react to 2 Na₃P
Then 89.7 moles of SrO may react to (89.7 . 2) /3 = 59.8 moles of Na₃P
We convert the moles to mass (mass . molecular weight)
59.8 mol . 99.9 g /mol = 5974 g

Please read the below paragraphs and then answer the 2 questions in complete sentences.
Natural selection was proposed by Charles Darwin to explain how new species evolve. All types of living things have small differences between the individuals in the species. If one of those differences allows the individual to live longer, they will likely have more offspring. As that trait is passed on, the population starts to look more like the successful individual. Over time, the species changes.
In 1896, J. W. Tutt suggested that the peppered moths were an example of natural selection. He recognized that the camouflage of the light moth no longer worked in the dark forest. Dark moths live longer in a dark forest, so they had more time to breed.
1. What is natural selection?
2. How are peppered moths an example of natural selection?
FOLLOW THE INSTRUCTIONS PLZZZ
1.Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
2.Because predators were able to spot the light moths more easily, the dark moths were more likely to survive and reproduce. ... The peppered moth case is an example of natural selection. In this case, changes in the environment caused changes in the characteristics that were most beneficial for survival

Answer:
Explanation:
If another predator was introduced to this food web, this food web would fail because it won't be balanced well. Let's say the predator eats more food than the eagle. Then the eagle would have less food for itself, and it might go endangered, and vice versa if the eagle eats more. Either way, this would cause almost no worms left and that means there would be an overflow of the rats because there would be no worms for them to be eaten by. This would cause a shortage of crops as well.

help pleaseeee. over dilutions in chemistry
Answer:
5 L
Explanation:
We'll begin by calculating the molarity of the CaCl₂ solution. This can be obtained as follow:
Mole of CaCl₂ = 0.5 mole
Volume = 2 L
Molarity =?
Molarity = mole /Volume
Molarity = 0.5 / 2
Molarity = 0.25 M
Finally, we shall determine the volume of the diluted solution. This can be obtained as follow:
Molarity of stock solution (M₁) = 0.25 M
Volume of stock solution (V₁) = 2 L
Molarity of diluted solution (M₂) = 0.1 M
Volume of diluted solution (V₂) =?
M₁V₁ = M₂V₂
0.25 × 2 = 0.1 × V₂
0.5 = 0.1 × V₂
Divide both side by 0.1
V₂ = 0.5 / 0.1
V₂ = 5 L
Thus the volume of the diluted solution is 5 L

10.00 g of O2 reacts with 20.00 g NO Determine the amount of NO2, limiting reactant, and the excess reactant.
Answer:
Limiting reactant: O₂
Excess reactant: NO
Amount of NO₂ produced: 28.75 g
Explanation:
The balanced equation for the reaction between O₂ and NO to produce NO₂ is the following:
O₂(g) + 2NO(g) → 2NO₂(g)
According to the equation, 1 mol of O₂ reacts with 2 moles of NO to produce 2 moles of NO₂.
We first convert the moles of each compound to mass by using the molecular weight (MW):
MW(O₂) = 16 g/mol x 2 = 32 g/mol
⇒ mass O₂ = 1 mol O₂ x 32 g/mol O₂ = 32 g
MW(NO) = 14 g/mol + 16 g/mol = 30 g/mol
⇒ mass NO = 2 mol NO x 30 g/mol NO = 60 g
MW(NO₂) = 14 g/mol + (2x 16 g/mol) = 46 g/mol
⇒ mass NO = 2 mol NO₂ x 46 g/mol NO₂ = 92 g
For the reactants, the stoichiometric ratio is 32 g O₂/60 g NO. Thus, the mass of O₂ required to completely react with 20.00 g of NO is:
mass of O₂ required = 20.00 g NO x 32 g O₂/60 g NO = 10.67 g O₂
We need 10.67 g of O₂ and we have only 10.00 g, so the limiting reactant is O₂. Thus, the excess reactant is NO.
With the limiting reactant, we calculate the amount of product produced (NO₂). For this, we consider the stoichiometric ratio 92 g NO₂/32 g O₂:
mass of NO₂ produced = 10.00 g O₂ x 92 g NO₂/32 g O₂ = 28.75 g NO₂

A reaction between 1.7 moles of zinc Ipdide and excess sodium carbonate ylelds 12.6 grams of zinc carbonate. This is the equation for the
reaction:
Na2CO3 + Zniz - 2Nal +
ZnCoz.
What is the percent yield of zinc carbonate?
The percent yield of zinc carbonate is
5.91
1X.
Answer: The percent yield of zinc carbonate is 5.91 %
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} ZnCO_3=\frac{12.6 g}{125.4g/mol}=0.100moles[/tex]
[tex]ZnI_2[/tex] is the limiting reagent as it limits the formation of product and [tex]Na_2CO_3[/tex] is the excess reagent.
[tex]Na_2CO_3+ZnI_2\rightarrow 2NaI+ZnCO_3[/tex]
According to stoichiometry :
1 mole of produce = 1 mole of
Thus 1.7 moles of [tex]ZnI_2[/tex] will produce=[tex]\frac{1}{1}\times 1.7=1.7moles[/tex] of [tex]ZnCO_3[/tex]
Theoretical yield of [tex]ZnCO_3=moles\times {\text {Molar mass}}=1.7moles\times 125.4g/mol=213.2g[/tex]
percentage yield = [tex]\frac{\text {Experimental yield}}{\text {Theoretical yield}}\times 100=\frac{12.6g}{213.2g}\times 100=5.91\%[/tex]

Answer:
1. Mass of KCl produced = 774.8 g of KCl
2. Mass of KNO₃ produced = 13.837g
3. Moles of NaOH made = 0.846 moles
4. Moles of LiCl produced = 0.846 moles
5. Moles of CO₂ produced = 207.6 moles
Explanation:
1. From the equation of reaction, 1 mole of ZnCl₂ produces, 2 moles of KCl.
5.02 moles of ZnCl₂ will produce, 2 × 5.02 moles of KCl = 10.4 moles of KCl
Molar mass of KCl = (39 + 35.5) g/mol = 74.5 g/mol
10.4 moles of KCl = 10.4 × 74.5 g
Mass of KCl produced = 774.8 g of KCl
2. Mole ratio of KNO₃ and KOH = 1:1
O.137 moles of KOH will produce 0.137 moles of KNO₃
Molar mass of KNO₃ = 101 g/mol
Mass of KNO₃ produced = 0.137 × 101 g = 13.837g
3. Molar mas of Ca(OH)₂ = 74.0 g
Moles of Ca(OH)₂ in 31.3 g = 31.3/74.0 = 0.423 moles of Ca(OH)₂
Mole ratio of NaOH and Ca(OH)₂ in the reaction = 2 : 1
Moles of NaOH made = 2 × 0.423 = 0.846 moles
4. Molar mass of MgCl₂ = 95.0 g
Moles of MgCl₂ in 40.2 g = 40.2/95.0 = 0.423 moles
From the reaction equation, mole ratio of MgCl₂ and LiCl = 1:2
Moles of LiCl produced = 2 × 0.423 = 0.846 moles
5. From the equation of reaction, 1 mole of C₆H₁₀O₅ produces 6 moles of cO₂
34.6 moles of C₆H₁₀O₅ will produce 34.6 × 6 moles of CO₂
Moles of CO₂ produced = 207.6 moles
