this is the one i found.....
Answer:
55.18 L
Explanation:
First we convert 113.4 g of NO₂ into moles, using its molar mass:
- 113.4 g ÷ 46 g/mol = 2.465 mol
Then we<u> use the PV=nRT formula</u>, where:
- P = 1atm & T = 273K (This means STP)
- R = 0.082 atm·L·mol⁻¹·K⁻¹
Input the data:
- 1 atm * V = 2.465 mol * 0.082atm·L·mol⁻¹·K⁻¹ * 273 K
And <u>solve for V</u>:
Answer:
i believe it's C
Explanation:
the result of multiplying (2.5 * 1010) and (3.5 x 10-7) is 8.8.10^3
Given
Mass number of isotope = 63
Number of neutrons = 33
So number of protons = 63 - 33 = 30
Hence atomic number of metal = 30
thus metal is = zinc
now as it is forming cation with 28 electrons it means it has lost two electrons so it must have a dipositive charge
the symbol of metal ion will be
Zn^+2
Answer:
is this a T or F question? if so then T
