Jane made this picture to represent a chemical reaction:

Two circles, one white and the other gray are shown on the left. A small portion of the two circles overlap and the label below the circles is XY. An arrow pointing right is shown on the right of the overlapping circles. There are two circles on the right of the arrow, one white and the other gray, and there is a plus sign between them. The white circle is labeled X and the gray circle is labeled Y.

Which of the following statements best explains the type of chemical reaction represented by Jane's picture? (5 points)

It represents a synthesis reaction because one combined reactant forms multiple products.

It represents a synthesis reaction because the same atoms are present in the reactants and products.

It represents a decomposition reaction because one reactant breaks apart and forms two products.

It represents a decomposition reaction because the total mass of the products is less than the mass of the reactant.

Answers

The reaction represents a decomposition reaction because XY is broken into its constituents.

A decomposition reaction is one in which the reactant is broken up into its constituents. In this case, the reactant is XY. The reactant is shown in the left hand side. The reactant is broken up to yield the products. X and Y.

Since the reactant was broken up into the one white and one gray circles labelled X and Y, then the reaction is a decomposition reaction.

a 7.221 g sample of a compound contains 1.990 g carbon, 2.341 g hydrogen, and the rest is oxygen. Determine the
percent composition of the compound

Answers

Answer:

17.19%

Explanation:

mass of oxygen = 7.221 - (1.990 + 2.341)

= 2.890g

Empirical formula of the compound

For carbon,

1.990/12 = 0.1658

For hydrogen,

2.341/1 = 2.341

For oxygen,

2.890/16 = 0.1806

0.1658 ÷ 0.1658 = 1

2.341 ÷ 0.1658 = 14.11

0.1806 ÷ 0.1658 = 1.089

Empirical formula of the compound= CH14O

Molar mass= (1×12) + (14×1) + (1×16)

= 12+14+16

= 42g/mol

percentage composition= 7.221/42 × 100

= 17.19%

Which of the following liquids has the highest viscosity
A water
B oil
C milk
D honey

Answers

Answer:

honey has the highest viscosity

According to the given option, honey is the liquid that has the highest viscosity. So, the correct option is D.

What do you mean by Viscosity?

Viscosity may be defined as the effects of a liquid by probity of which an internal resistance comes into play when the liquid is in movement and resists the comparable motion between its distinct layers.

Among all the given options, honey possesses more strong intermolecular attractive forces that result in the high compaction of particles in the honey.

After honey, Oil is more viscous followed by milk, and then water.

Therefore, the correct option for this question is D.

None of Substance B is visible in the second beaker. Which of the following statements is true?

B. Substance A is more soluble in water than Substance B


C. Substance A is less soluble in water than Substance B


D. Substance A is not soluble in water

Answers

Substance A is less soluble in water than Substance B.

In this experiment, we can see that small amount of substance A is present at the bottom of the beaker which means that some amount of substance A does not dissolve in water.

While on the other hand, no substance B is present at the bottom of beaker which shows that all the substance B is dissolved in water so we can made a conclusion that Substance A is less soluble in water than Substance B.

Answers

Taking into account the Brønsted-Lowry acid-base theory, a base/conjugate acid pair is H₂O/H₃O⁺.

The Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.

According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.

So, reactions between acids and bases are H⁺ proton transfer reactions, causing the acid to form its conjugate base and the base to form its conjugated acid by exchanging a proton.

In other words, a conjugate base is an ion or molecule resulting from the acid that loses the proton, while a conjugate acid is an ion or molecule resulting from the base that gains the proton:

acid + base ⇄ conjugate base + conjugate acid

In this case, you know:

H₂PO₄ + H₂O → H₃O⁺ + HPO₄⁻

H₂PO₄ behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.

So, H₃O⁺ is the conjugate acid of the H₂O and HPO₄⁻ is conjugate base of H₂PO₄.

In summary,  a base/conjugate acid pair is H₂O/H₃O⁺.

Light is very important for photosynthesis and the overall well-being of plants. In a tight space, light and air become limited. This means that plants growing in such a space will not be able to photosynthesize optimally.

We know that

Molar mass of Sodium (Na) = 23 g/mol

Molar mass of Oxygen (O) = 32 g/mol

Molar mass of Hydrogen (H) = 2 g/mol

So,

Mass of 1 mole of NaOH

=> 1 × 23 + 1 × 16 + 1 × 1

=> 23 + 16 + 1

=> 40 g/mol
