Answer: Most polyatomic ions are -ate, related ions that have 1 fewer oxygen atom are -ite (must have at least 1 oxygen tho) and nonmetals are ide.
Explanation:
Answer:
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom.
Answer:
Final volume is 1.29cm³
Explanation:
Using combined gas law:
P₁V₁/T₁ = P₂V₂/T₂
<em>Where P is pressure, V volume and T absolute temperature of 1, initial state and 2, final state of a gas.</em>
<em />
We can solve the volume of the gas:
P₁ = 1atm at STP
V₁ = 1cm³
T₁ = 273.15K at STP
P₂ = 710mmHg * (1atm / 760mmHg) = 0.9342atm
V₂ = ?
T₂ = 55.0°C + 273.15K = 328.15K
Replacing:
1atm*1cm³/273.15K = 0.9342atm*V₂/328.15K
1.29cm³ = V₂
<h3>Final volume is 1.29cm³</h3>

Answer is: <span>the objects potential energy is 24500 J.
</span>m(object) = 50 kg.
h(object) = 50 m.
g = 9,8 m/s².
E(object) = m·g·h.
E(object) = 50 kg · 9,8 m/s² · 50 m.
E(object) = 24500 N·m = 24500 J = 24,5 kJ.
g - <span>the acceleration of free fall.
mg - </span><span>weight of the object.</span>
Mg 10.9g/24.31=0.018/0.018=1
Cl 31.8g/35.45=0.897/0.018=49.83=50
O 57.3g/16.00=3.581/0.018=198.94=199
empirical formula=MgCl50O199
I think it's right
