Atomic fission requires temperatures of one million degrees or hotter.<br><br> True <br> False
pickupchik [31]

<u>Answer:</u> The correct answer is false.

<u>Explanation:</u>

Atomic fission reactions are defined as reactions in which nucleus of an atom splits into two or more smaller nuclei. These reactions are carried out in nuclear reactors. The temperature range for the reactors are around 300°C.

Atomic fusion reactions are the reactions in which nucleus of two or more atoms fuse together to form one large nuclei. These reactions require a huge amount of energy to occur. The temperature required by these reactions are about one million kelvins.

Hence, the given statement is False.

pentagon [3]

8%

Explanation:

In a DNA molecule the no. of Adenine bases equal to that of Thymine bases

The no. of Cytosine bases equal to that of Guamine bases.

If we take no. of Thymine bases as x and no. of Cytosine bases as y,

Adenine + Thymine + Cytosine + Guamine = 100

x + x + y+y = 100

2( x+y) = 100

x+y = 50

y=42

therefore x= 50-42 = 8%

You have 100 grams of potassium fluoride (KF) .
laiz [17]

Answer:

Option C = 1.72 mol

Explanation:

Given data:

Mass of KF = 100 g

Moles of KF = ?

Solution:

First of all we have to calculate the molar mass of KF.

Molar mass of KF = 39.0983 g/mol + 18.998403 g/mol

Molar mass of KF = 58. 0967 g/mol

Formula:

Number of moles = mass/molar mass

Number of moles = 100 g/ 58.0967 g/mol

Number of moles = 1.72 mol
