What is the relationship between the mass of the boat and the mass of the displaced liquid?

Chemistry
1 answer:
Greeley [361]3 years ago
7 0
Answer: The mass of the displaced liquid is equal to the volume of the liquid multiplied by its density. When a boat is placed in water, the volume of displaced water is equal to the mass of the boat.

I hope this helped!

zvonat [6]

Answer:

1) D; 2) B

Explanation:

1) <em>Conservation of atoms </em>

D is correct.

It has four atoms of H and two of O on each side of the reaction arrow.

A. <em>Wrong</em>. It has the same number of H and O on each side, but it has the <em>wrong product</em>. The reaction forms O₂ molecules, not O atoms.  

B. <em>Wrong</em>. Atoms are balanced, but the <em>products are incorrect</em>.

C. <em>Wrong</em>. Atoms are balanced, but the <em>reactants are incorrect</em>.

===============

2) <em>Chemical equations </em>

B is correct.

The atoms are balanced, and the equation shows the correct formulas of the molecules.

A. <em>Wrong</em>. Atoms are balanced, and the formulas are correct, but the equation is <em>not in its simplest form</em>. The coefficients are not in their lowest terms. We must divide every coefficient by six to get the correct equation: H₂ + Cl₂ ⟶ 2HCl.

C. <em>Wrong</em>. The <em>reactants are incorrect</em>, and the equation is <em>not in its lowest terms</em>.

D. <em>Wrong</em>. The <em>reactants are incorrect</em>.

A mixture of gaseous CO and H2, called synthesis gas, is used commercially to prepare methanol (CH3OH), a compound considered an
Anit [1.1K]

<u>Answer:</u> The value of K_c for the reaction at 550.3 K is 247.83

<u>Explanation:</u>

Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_{c}

For a general chemical reaction:

aA+bB\rightarrow cC+dD

The expression for K_{c} is written as:

K_{c}=\frac{[C]^c[D]^d}{[A]^a[B]^b}

The chemical equation for the production of methanol follows:

CO+2H_2\rightleftharpoons CH_3OH

The expression of K_c for above equation follows:

K_c=\frac{[CH_3OH]}{[CO][H_2]^2}

We are given:

[CH_3OH]=0.0401mol/L

[CO]=0.02722mol/L

[H_2]=0.07710mol/L

Putting values in above equation, we get:

K_c=\frac{0.0401}{0.02722\times (0.07710)^2}\\\\K_c=247.83

Hence, the value of K_c for the reaction at 550.3 K is 247.83

HELP ASAP!! how can nuclear energy be classified as an inexhaustible energy resource??
seropon [69]

Answer:

No, and yes. As there is a finite amount of matter in the

universe, only so much can be converted to make energy. There will

be a limit, though it is a long, long way from where we are
