Answer:

Mass = 785.9 g

Explanation:

Given data:

Atoms of gold = 2.4 × 10²⁴ atoms

Mass of gold = ?

Solution:

First of all we will convert the number of atoms into moles.

2.4 × 10²⁴ atoms × 1 mol/ 6.02 × 10²³ atoms

number of moles = 3.99 mol

Now we will determine the mass of gold.

Mass = number of moles × molar mass

Mass =  3.99 mol × 196.97 g/mol

Mass = 785.9 g

Which choice can be a solid, liquid, or a gas?
Katena32 [7]

I believe that your option C would be the correct answer. We know that water can turn to a solid materail because during cold temperatures, water turns to ice.

We know that water can turn to gas, as water can evaporate.

And also, we know that water is obviosly a liquid.

Therefore, Option C would be your answer.

If 725 ml of N² gas is at 1 atm, what volume will it have at 1.4 atm?​
alexdok [17]

Answer:

518 mL

Explanation:

We can solve this using Boyle's Law Formula

P1V1 = P2V2

where p1 = initial pressure, p2 = final pressure, v1 = initial volume and v2 = final volume

here , the initial pressure is 1 atm and the initial volume is 725mL

we are given the final pressure 1.4 and we need to find the final volume

so we have p1v1 = p2v2

==> plug in p1 = 1 , v1 = 725 mL and p2 = 1.4

(1)(725) = (1.4)v2

==> multiply 1 and 725

725 = (1.4)(v2)

==> divide both sides by 1.4

v2 = 518

N2 would have a volume of 518mL at 1.4atm

In order to predict the outcome of the reaction, write the molecular, full ionic, and net ionic equations for a mixture of aqueo
Elina [12.6K]

Answer:

See explanation

Explanation:

Full molecular equation;

2NH3(aq) + AgNO3(aq) -------> [Ag(NH3)2]NO3(aq)

Full ionic equation

2NH3(aq) + Ag^+(aq) + NO3^-(aq) --------> [Ag(NH3)2]^+(aq) + NO3^-(aq)

Net ionic equation;

2NH3(aq) + Ag^+(aq) -------->  [Ag(NH3)2]^+(aq)

When Silver nitrate is mixed with a solution of aqueous ammonia, a white and cloudy solution was observed.

Answer:

U= 238g/mol

U2O5= 556g/mol

Explanation:

Since U= 238

O=16

U3O5= 2(238)+3(16)=556g/mol
