Answer:
If Earth was tilted much less on its axis, it would lead to minor changes in precipitation and temperatures as Earth moves slightly towards and away from the sun.
Explanation:
If a planet tilts more, it leads to colder winters and warmer summers. However, if a planet tilts less, it leads to less severe seasons that is and milder winters and cooler summers.
If Earth was tilted much less on its axis, it would lead to minor changes in precipitation and temperatures as Earth moves slightly towards and away from the sun.
The pressure of a gas is 750 torr when its volume is 400. ml. Calculate the
pressure in atm if the gas is allowed to expand to 600.0 mL at a constant
temperature.
a. 0.66 atm
b. 1.5 atm
c. 500. atm
d. 1130 atm
Answer:
a. 0.66 atm
Explanation:
Pi = 750 torr = 0.99 atm. Pf = ?
Vi = 400 ml Vf = 600ml
Using PiVi = PfVf
Then 400ml × 0.99atm = Pfatm × 600ml
Solving for Pf, we have,
Pf = (400ml × 0.99atm)/600ml
Pf = 0.66atm

What happen if your Adrenal Glands become overprotective of underproductive?
What happen if your Adrenal Glands become overprotective of underproductive?
Answer: if your adrenals becomes overproductive it will lead to a health issue known as CUSHING'S SYNDROME while when they become underproductive it will lead to a health condition known as ADDISON'S DISEASE.
Explanation:
The adrenal glands are divided into two embryologically and functionally distinct parts: the adrenal cortex and adrenal medulla.
The adrenal cortex is part of the hypothalamic - pituitary - adrenal endocrine system. Morphologically, the adult adrenal cortex consists of three layers which include:
--> The outer thin layer: this is also called zona glomerulosa. It secrets only aldosterone.
--> The inner two layers: these comprises of the zona fasciculata and zona reticularis. They both form a functional unit and secrete most of the adrenocortical hormones.
The adrenal medulla is the inner part of the adrenal gland which secrets the adrenaline and noradrenaline hormones.thry take part in sympathetic nervous system.
When the adrenal glands become a OVERPRODUCTIVE, the adrenal cortex is highly affected. This may occur due to hyperstimulation of the adrenal gland by adrenocorticotrophic hormone,either from the pituitary gland or from an ectopic source or due to largely autonomous secretion by an adrenal tumor such as an adenoma or carcinoma. The increased endogenous cortisol production leads to a disorder known as CUSHING'S SYNDROME. The clinical and metabolic features include obesity, hyperglycaemia and hypertension.
Also when the adrenal glands become UNDERPRODUCTIVE, a health condition known as ADDISON'S DISEASE may occur. This is cause any the bilateral destruction of all zones of the adrenal cortex, usually as the result of an autoimmune process or mycotic infections. The resulting decrease in cortisol production may lead to clinical features such as hypotension, hypoglycemia, nausea and vomiting.
9. The verb corrode means 'wear away gradually, usually by a chemical reaction." A metal
that is prized for its "resistance to corrosion" has what property?
A metal that is prized for its resistance to corrosion has what property?
Answer:
The metal has a high resistance to corrosion, meaning it is more durable and will nor rust easily.
Explanation:
The verb "corrode" means the condition of being damaged easily. In other words, it means that the metal or item gets worn out easily and is not long-lasting.
So, when metal is prized for its resistance against corrosion, it means that the metal is strong and does not wear out easily. It can outstand and withheld the corrosion effect longer. This means that the metal is durable and will not corrode easily.

Explain how the digestive/excretory system is similar to a recycling center
Answer:
The digestive system is a system where our body breaks down food to acquire important nutrients. This is the same as your local recycling center because they collect and breaks the plastic down to be reused into recycled products.
The excretory system is a system where we remove excess unnecessary materials. This can be the same as the recycling center because they remove unnecessary materials (such as trash that is not meant to be recycled).

Make up a short story to explain jays speed and acceleration change throughout his walk. Make sure to address parts A-D
Answer:
Speed of jays increases first, again increases, decreases and then increases.
Explanation:
The speed of jays increases while moving from rest to point A and no acceleration due to constant speed. From point A to point B, the speed is continues to increase and no acceleration. From point B to point C, the speed of jays decreases and acceleration is produced in the journey due to change of speed and from point C to point D, the speed of jays again increases and acceleration is produced due to increasing the speed.
Answer:
The speed of jay's walk increases first, again increases, then it decreases and then increases due to his acceleration walk during parts A-D.

If a 0.7 M solution of Ca(OH)2 dissociates completely in water, what is the
final [OH-]?
Answer:
1.40 M [OH⁻]
Explanation:
This compound dissociates into 3 ions, but since we are asked about [OH⁻], it's only 2. Therefore, multiply the molarity of the solution by the number of ions that [OH⁻] dissociates into:
2 × 0.70 M = 1.40 M

Calculate the percentage composition of SrBr2
Answer:
64.6% of Br and 35.4% of Sr
Explanation:
The percentage composition is obtained defining the percentage in mass of each atom in a molecule.
To solve this question we must find the mass of each atom in 1 mole:
Molar mass Br: 79.904g/mol
Molar mass Sr: 87.62g/mol
The molar mass of SrBr2 is:
79.904g/mol*2 + 87.62g/mol =
159.808g/mol + 87.62g/mol =
247.428g/mol
The percentage of Br is:
79.904g/mol*2 = 159.808g/mol / 247.428g/mol * 100
= 64.6% of Br
And percentage of Sr is:
87.62g/mol / 247.428g/mol * 100
= 35.4% of Sr

25 ml of 2.4 M K2(CO3) is mixed with 35 ml of 2.0 M Al(NO3)3. (a) Evaluate the moles for each reactant (b) indicate the limiting reactant (c) how many moles of Al2(CO3)3 are formed?
Answer:
a) 0.06 mol K₂(CO₃) and 0.07 mol Al(NO₃)₃
b) The limiting reactant is K₂CO₃
c) 0.03 moles of Al₂(CO₃)₃
Explanation:
The balanced reaction between K₂CO₃ and Al(NO₃)₃ is the following:
3 K₂CO₃ + 2 Al(NO₃)₃ → Al₂(CO₃)₃ + 6 KNO₃
(a) We can calculate the moles for each reactant as the product of the molarity (M) and the volume (V) in liters.
K₂(CO₃): M = 2.4 mol/L , V = 25 mL x 1 L/1000 mL = 0.025 L
⇒ moles K₂(CO₃) = M x V = 2.4 mol/L x 0.025 L = 0.06 mol K₂(CO₃)
Al(NO₃)₃: M = 2.0 mol/L , V = 35 mL x 1 L/1000 mL = 0.035 L
⇒ moles Al(NO₃)₃ = M x V = 2.0 mol/L x 0.035 L = 0.07 mol Al(NO₃)₃
(b) According to the balanced equation, the stoichiometric ratio is 3 moles K₂CO₃/2 moles Al(NO₃)₃. We have 0.07 moles of Al(NO₃)₃, so we multiply the moles of Al(NO₃)₃ by the stiochiometric ratio to calculate how many moles of K₂CO₃ are needed:
0.07 mol Al(NO₃)₃ x 3 mol K₂CO₃/2 mol Al(NO₃)₃ = 0.105 moles of K₂CO₃
We need 0.105 moles of K₂CO₃ but we have only 0.06 moles of K₂CO₃. Therefore, the limiting reactant is K₂CO₃.
(c) We use the limiting reactant to calculate how many moles of product (Al₂(CO₃)₃) are formed. According to the equation, 2 moles of K₂CO₃ produce 1 mol of Al₂(CO₃)₃, thus the stoichiometric ratio is 1 mol Al₂(CO₃)₃/2 moles K₂CO₃. We have 0.06 moles of K₂CO₃, so the number of moles of Al₂(CO₃)₃ will be:
0.06 moles K₂CO₃ x 1 mol Al₂(CO₃)₃/2 moles K₂CO₃ = 0.03 moles of Al₂(CO₃)₃

A solution of KOH is prepared with a [OH-] concentration of 3.3 × 10-2 M. Calculate [H+], pH, and identify whether the solution is acidic, basic, or neutral.
Answer:
[H⁺] = 3.03x10⁻¹³ MpH = 12.52The solution is basicExplanation:
We can first calculate [H⁺] by using the formula:
[H⁺] * [OH⁻] = 1x10⁻¹⁴[H⁺] * 3.3x10⁻² = 1x10⁻¹⁴[H⁺] = 3.03x10⁻¹³ MNow we proceed to calculate pH:
pH = -log [H⁺]pH = -log (3.03x10⁻¹³)pH = 12.52As the pH is higher than 7, the solution is basic.
