Answer:
In CO, the oxidation number of C is (+2), and that of O is (-2).
In H_2H2 , the oxidation number of H is (0).
In CH_3OHCH3OH , the oxidation number of C is (-2), that of O is (-2) and that of H is (+1).
Explanation :
Oxidation number : It is also called oxidation state. It is a number assigned to an element in a chemical compound that represent the number of electrons gained or lost by an element in a compound.
Answer:
volume of box is 38.81 cm³.
Explanation:
Given data:
Width of box = 4.5 cm
Height of box = 5.750 cm
Length of box = 1.50 cm
Solution:
Formula:
Volume = length × height × width
by putting values,
V = 1.50 cm × 5.750 cm× 4.5 cm
V = 38.81 cm³
Thus, the volume of box is 38.81 cm³.
Characteristics of pea plants are determined by genes inherited from both the parents.
Option 4.
<h3><u>Explanation:</u></h3>
Gregor Johann Mendel is also called as the father of Genetics. Mendel experimented on the pea plants to determine what happens when different types of pea plants are crossed between themselves and what actually determines the characteristics of the pea plants. After two types of experiments, he came to a conclusion that there are certain substances which he named as '' factors'' which are actually inherited from the parents. He also told that there are certain type of factors which are dominant over the others which he termed as recessive factors. So, the characteristics of the progenies depend on both the factors inherited from both the parents.
Answer:
See explanation
Explanation:
CO2 reacts with water to form carbonic acid as follows;
CO2(g) + H2O(l) ---------> H2CO3(aq)
This makes the solution more acidic hence it will require more NaOH to reach end point due to the increase in acidity.
Hence, if CO2 is not removed by boiling the solution, a greater amount of NaOH is required to reach end point.
Based on my information, this would be known to be a "green house" as this, would be as it would be a house known for planting, and etc. But the main part that I wanted to consider would be the fact that it would also be a "closed system" as you would be able to open and close this kind of machine.
Your answer: a greenhouse
