- The mass in kilograms is (11971.98 Kg)
- Pounds can be converted to pounds to kilograms by using this conversation (1 pound = 0.454 kilogram)
<em />
- <em>Let X= mass of the object in kilograms</em>
- <em>(1 pound = 0.454 kilogram)</em>
- 26370 pounds = X kilograms
- <em>If we cross multiply, we have </em>
- (0.454 kilogram × 26370 pounds) = X kilograms
X = 11971.98 Kg
- Therefore, mass in kilograms is (11971.98 Kg)

Answer:
A barium atom would be expected to contain 2 electrons in its outer energy level.
Explanation:
The columns of the periodic table are called groups. There are eighteen groups, numbered from 1 to 18.
The elements of each group have the same number of electrons in their last atomic shell, which is why they have similar chemical properties, because the chemical properties of chemical elements are strongly related to the electrons located in the last atomic shell.
That is, in a group, the chemical properties are very similar, because all the elements of the group have the same number of electrons in their last or last shells.

<span>Answer: 17.8 cm
</span>
<span>Explanation:
</span>
<span>1) Since temperature is constant, you use Boyle's law:
</span>
<span>PV = constant => P₁V₁ = P₂V₂
</span><span>=> V₁/V₂ = P₂/P₁</span>
<span>
2) Since the ballon is spherical:
</span><span>V = (4/3)π(r)³</span>
<span>
Therefore, V₁/V₂ = (r₁)³ / (r₂)³
</span>
<span>3) Replacing in the equation V₁/V₂ = P₂/P₁:
</span><span><span>(r₁)³ / (r₂)³ </span>= P₂/P₁</span>
<span>
And you can solve for r₂: (r₂)³ = (P₁/P₂) x (r₁)³
</span>(r₂)³ = (1.0 atm / 0.87 atm) x (17 cm)³ = 5,647.13 cm³
<span>
r₂ = 17.8 cm</span>
Answer:
38.7 g
Explanation:
first you find the molar mass of Nickle(II) Perchlorate
Nickle = 58.693 g/mol
Perchlorate is Chlorine and Oxygen combined
Molar mass of chlorine is 35.453 g/mol
Oxygen = 15.999 g/mol but since it has 4 oxygen atoms combined with chlorine you have to multiply 15.999 by 4 which is 63.996 add all the masses together and that gives you 158.142. Since you have moles you multiply the moles by the molar mass which looks like this. 0.245 * 158.142 which equals 38.74479 but with sign figs it is 38.7g as your final answer. Ask me if you are confused about something.
