Chlorine + Calcium --> Ionic Bond
Iron cannot covalently bond as it is a metal
A vice, you can tighten it and then work on what is held in it without having to hold it still or in the position you want.
Answer:
Dipole dipole interaction
Explanation:
Answer:
grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
Explanation:
The molecular weight of acetylene is 26.04 g/mol
Molecular weight of carbon is equal to 12.011 g/mol
Two carbon atom produces one acetylene molecule.
Thus, 2 * 12.011 g/mol of carbon is used to produce 26.04 g/mol of acetylene,
Amount of carbon required to produce 59.8 grams of acetylene
grams/mol
grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
Answer:
The answer is

Explanation:
The energy of a photon can be found by using the formula
<h3>E = hv</h3>
where
E is the energy
v is the frequency
h is the Planck's constant which is
6.626 × 10-³⁴ Js
From the question
v = 5.0 × 10¹⁴ Hz
So the energy is

We have the final answer as
