Answer:
hope this helps :)
Explanation:
for the first one, you can look at the periodic table and look at the atomic number and it will show you how many protons there are giving you the answer because protons and electrons are equal in a pure element
a- carbon
b- neon
c- boron
d- oxygen
e- helium
f- hydrogen
g- lithium
h- beryllium
i- nitrogen
1- sulfur
2- S
3- 16
4- 32.066
5- 16
6- 16
7- 16.066
8- draw circles and put 16 dots like on the other page and in the middle put 16 nuetrons and electrons
9- 6 i think
Answer:
The correct answer to your question is letter A
Explanation:
a. [ Ca: ] This structure is correct because Calcium has 2 valence electrons and in this structure we can see them as points to the right side of the symbol.
b. [ Ca ]2+ This option is not correct, in Lewis dot representation, electrons are points and this structure do not show them.
c. No right choice. This option is wrong because letter A is correct.
Answer:
a. Synthesis reaction
b. Single - Displacement
c. Decomposition reaction
d. Combustion Reaction
Explanation:
Synthesis reaction: Reaction in which two or more substance combine to give a single compound.
Single - Displacement : Reaction in which the more reactive element displaces the less reactive element.Here Li replace OH from water.
Decomposition reaction: Reaction in which a single reactant decompose to give two or more products.
Combustion Reaction : IT is a redox reaction in which a substance is burned in the presence of oxygen to give carbon dioxide and water.
Incase of gases if we will reduce the temperature or if. we apply pressure on gas it will liquify

Answer:
The possible genotypes of a man with blood type B are BB or BO and the genotype of a woman with blood type AB is AB. The child would receive an A allele or a B allele from the mother and a B allele or an O allele from the father. Therefore, the child could not possibly be of blood type O.
