Two substances in a mixture differ in density and particle size. theses properties can be used to

Answers

Answer:

option 1. Two substances in a mixture differ in density and particle size. These properties can be used to separate the substances. These properties can be manipulated in order to have a better separation between the two substances.

Explanation:

Answer:

Two substances in a mixture differ in density and particle size. These properties can be used to separate both of them using the separating funnel or using filtration (filter paper).

Explanation:

Since their densities are different, one substance should float above the other in the mixture which allows for the separating funnel to let the substance sinking below (with the heavier density) to flow out first before changing the beaker to let the lighter substance flow out.

The substance with a bigger particle size would not be able to pass through the filter paper unlike the substance with the smaller particle size as the filter paper's pores is not big enough for it to pass through, separating both substances (with one on the paper and the other outside the filter paper, preferably in the beaker placed below the paper).

What is it called when elements combine to form a chemical compound?

Answers

Explanation:

A compound is a unique substance that forms when two or more elements combine chemically.Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons.

Blaire is teaching her little brother to ride his bike. She uses 7 N of force to push a 14 kg bike. What is the acceleration?
98 m/s2
0.5 m/s2
21 m/s2
2 m/s2

Answers

Answer:

The solution is

Explanation:

a = f/m

a =7/14

a=1/2

a=0.5

Acceleration of bike is 0.5 m/s²

Given that:

Force used in push = 7 N

Mass of bike = 14 kg

Find:

Acceleration of bike

Computation:

Force = Mass × Acceleration

Force used in push = Mass of bike × Acceleration of bike

7 = 14 × Acceleration of bike

Acceleration of bike = 7 / 14

Acceleration of bike = 0.5 m/s²

2. How many liters of propane gas (C3H8) will undergo complete combustion with 34.0 L of oxygen gas? ___ C3H8 (g) + ___ O2 (g → ___ CO2 (g + ___ H2O(g

Answers

Answer:

6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.

Explanation:

Given;

combustion reaction of propane and oxygen;

C₃H₈ + O₂(g)  → CO₂(g)     + H₂O(g)

Balance the chemical reaction as follows;

C₃H₈ + 5O₂(g)  → 3CO₂(g)   +   4H₂O(g)

From the balanced equation;

1 mole of C₃H₈ ---------------- 5 moles of 5O₂(g)

x Liters of C₃H₈ ----------------- 34.0 Liters of O₂(g)

x = 34 liters / 5

x = 6.8 liters

Therefore, 6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.

How many molecules of H2O are in 8.54 moles of H2O?

a. 5.14 * 10^24 molecules H2O
b. 2.86 * 10^23 molecules H2O
c. 6.02 * 10^23 molecules H2O
d. 5.14 * 10^23 molecules H2O

Answers

Answer:

[tex]\boxed {\boxed {\sf A. \ About \ 5.14 *10^{24} \ molecules \ H_2O}}[/tex]

Explanation:

To convert from moles to units, we must use Avogadro's Number: 6.022 * 10²³

This tells us the number of units (molecules of water in this problem) in 1 mole of a substance (water). We can use it as a ratio or fraction.

[tex]\frac{6.022 *10^{23} \ molecules \ H_2O}{1 \ mol \ H_2 O}[/tex]

Now, we can multiply this fraction by the moles of water (8.54) given.

[tex]8.54 \ mol \ H_2O*\frac{6.022 *10^{23}\ molecules \ H_2O}{1 \ mol \ H_2 O}[/tex]

When we multiply, the moles of water will cancel out.

[tex]8.54 *\frac{6.022 \ molecules \ H_2O}{1 \ }[/tex]

Since the fraction has a 1 as a denominator, we can remove it. The problem will be a simple multiplication problem.

[tex]8.54*6.022 \ molecules \ H_2O[/tex]

[tex]5.142788*10^{24} \ molecules \ H_2O[/tex]

The original measurement of 8.54 has 3 significant figures (8, 5, and 4). Therefore, we must round our answer to 3 sig figs, which is the hundredth place in this case.

The 2 in the thousandth place tells us to leave the 4 in the hundredth place.

[tex]5.14 *10^{24} \ molecules \ H_2 O[/tex]

There are about 5.14*10²⁴ molecules of water in 8.54 moles.

Answer:

5.14 x 10^24 molecules of H2O.

Answers

Answer: D

Explanation: P = W/t

W = F d

When dividing, if you have a large number over a small, you get a large number. We want a small number, so we want the opposite for our P : W/ t formula. We want a small Work and a large time.

Right off the bat, the two with the least time aren't right then.

From there, we can estimate how much work it would take using the W = F d equation. If there is a small distance, there is less work, which is what we want to achieve a small work over large time.

So, the choice with the most time and the least distance should be correct.

15. An increase in atomic number is related to an increase in atomic mass because

a. more electrons are present in the atomic nucleus
b. more electrons are orbiting the atomic nucleus
c. more protons are present in the atomic nucleus
d. more protons are orbiting the atomic nucleus

Answers

Answer:

[tex]\boxed {\boxed {\sf C. \ More \ protons \ are \ present \ in \ the \ atomic \ nucleus}}[/tex]

Explanation:

First, let's define atomic number.

    ⇒ The number of protons in an atom.

    ⇒ This number determines the identity and properties of the atom

So, atomic number relates to protons. There is an increase in atomic number, so there must be more protons in the atom. We can eliminate choices A and B, because they pertain to electrons.

We are left with choices C and D. The difference between them is the location of the protons.

Protons are part of the nucleus of the atom: the dense, central region of the atom comprised of nucleons: protons and neutrons.

Electrons, not protons, orbit the nucleus, so  D is not correct.

We are left with choice C: more protons are present in the atomic nucleus
