Note: Above question is incomplete. Complete question is
<span>What type of chemical reaction is so3(g) + h2o(l) → h2so4(aq)
a) Neutralization
b) Decomposition
c) Combination
d) Single displacement reaction
...............................................................................................................
Solution:
In current context, following things may be noted
1) Neutralization reactions: In neutralization reactions, acid and base combine to form salt and water.
b) Decomposition reaction: R</span><span>eaction in which a single substance broken down two or more smaller substances is refereed as decomposition reaction. Decomposition reactions are characterized be present of single molecule on reactant side.
c) Combination reaction: In a recombination reaction</span><span> two or more molecules combine to form a single product.
d) Single displacement reaction: R</span><span>eaction in which an element within a compound is displaced by a another element is referred as single displacement reaction.
Above reaction satisfies the criteria of combination reaction, hence correct answer is option C, combination. </span>
Answer:
Environment refers to everything that surrounds an individual and interacts between them. The factors that control the environment can be biotic and abiotic.
Humans have greatly affected the environment. Some of the ways in which the environment is affected by humans are as follows-
(1) Humans have constructed industries and factories that have released a huge amount of toxic gases into the atmosphere.
(2) These harmful gases have increased the earth's global temperature. As a result of which the global warming effect has increased.
(3) The waste materials eliminated from these industries mix with the rivers and streams and pollute the water. It degrades water quality.
(4) The fossil fuels are exhausted at a very high rate.
(5) The spilling of the oils in the oceans has affected the marine species drastically.
(6) Due to the extensive mining at different places, soil fertility has decreased considerably.
(7) Cutting down trees for settlement purposes and other infrastructures.
Answer:
Coefficient
Explanation:
I am not that sure, but just wanted to help.
Answer:
Hybridization: sp
Electron geometry: linear
Molecular geometry: linear
Explanation:
H₃CCCH can also be written as its Lewis structure which is shown in the figure attached. The figure shows that the central carbon atom makes a single bond with CH₃ and a triple bond with CH. This means that the hybridization of the carbon is sp and both the electron and molecular geometry are linear with an 180° bond angle.

So what have I done here? First, I had a balanced chemical equation (this is the important step; is it balanced?). Then I used the stoichiometry to get the molar quantity of product, and converted this molar quantity to mass. If this is not clear, I am willing to have another go
