Atoms are attracted to each other because____

Answer:

A

Explanation:

Opposite charges attract therefore the electrons of one atom would be attracted by the nucleus (which contains protons). This heavily relies on a property called electronegativity. Which deals with the level of attraction a nucleus (the protons in the nucleus) have for electrons of other atoms.

What is the pressure in a 5.00 L tank with 49.00 grams of oxygen gas at 350 K? ___atm

ziro4ka [17]

Answer:

The right answer is "8.81 atm".

Explanation:

Given:

V = 5.00 L

Mass = 4900 g

MW = 32 g/mol

T = 350 K

Now,

Number of moles will be:

$n = \frac{Mass}{MW}$

$=\frac{49.00}{32}$

$=1.53125 \ mole$

By using the ideal gas equation, we get

⇒ $PV=nRT$

or,

⇒ $P=\frac{nRT}{V}$

By substituting the values, we get

$=\frac{1.53125\times 0.0821\times 350}{5.00}$

$=\frac{44.1}{5.00}$

$=8.81 \ atm$

SOMEONE PLS HELP

Gekata [30.6K]

Answer:

<h2>464.85 mL</h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we're finding the new volume

$V_2 = \frac{P_1V_1}{P_2} \\$

100.7 kPa = 100,700 Pa

95.1 kPa = 95,100 Pa

We have

$V_2 = \frac{100700 \times 439}{95100} = \frac{44207300}{95100} \\ = 464.8506...$

We have the final answer as

<h3>464.85 mL</h3>

Hope this helps you
