Answer:
Without a doubt, Africa is one of the most blessed continents on our planet in terms of both natural and human resources. So what are the causes of underdevelopment in Africa and possible solutions? The second most populous continent has an abundance of highly valuable minerals. It is therefore quite surprising that Africa is so backward when compared to most other continents. The reasons for this underdevelopment of Africa are varied hence it is important to outline as many of them as possible.
Explanation:
Just an example.. This can affect people because it can cause people to bring umbrellas wear rain coats of it were to rain.
Number of proton K=19
so, 42 - 19 =23
then the answer in 19 protons and 23 neutrons
You need to add the last substance to the products side(the right sode of the arrow). You have hydrogen and oxygen - water.
You get: BrO3 + N2H4 -> Br2 + N2 + H2O
# of Br: 1x1 = 1 # of Br: 2x1 = 2
O: 3x1 = 3 O: 1x1 = 1
N: 2x1 = 2 B N: 2x1 = 2
H: 4x1 = 4. H: 2x1 = 2
Br:
Multiply the reactant (left) side by 2 to balance.
O:
You've just multiplied the reactant oxygen by 2 so now the reactant side equals 6. Multiply the product (right) side by six as well.
H:
The product side is now equal to 12. Multiply the reactant side by 3 to balance.
N:
Now you have to balance N because the reactant side has been risen. So multiply the product side by three as well.
You end up with the complete and balanced equation:
2BrO3 + 3N2H4 -> Br2 + 3N2 + 6H2O
Answer: An object has a weight of 10 kg on the surface of Earth. If the same object were transported to the surface of Mars, the object would have a weight of 3.8 kg. The density of the object is greater on Earth than it is on Mars.
