The outer boundary of cell enclosing nucleus and cytoplasm is called cell membrane or plasma membrane.

<u>More to know</u> -

  • It is present in both plant and animal.
  • This membrane is living, thin, and delicate.
  • The cell membrane is a semi-permeable membrane, that allows the transmission of a very few molecules across it.

H3PO4 + Ca(OH)2 → Ca(H2PO4)2 + H2O
aniked [119]

Given question is incomplete. The complete question is as follows.

Balance the following equation:

H_3PO_4 + Ca(OH)_2 \rightarrow Ca(H_2PO_4)_2 + H_2O

Answer: The balanced chemical equation is as follows.

2H_3PO_4 + Ca(OH)_2 \rightarrow Ca(H_2PO_4)_2 + 2H_2O

Explanation:

When a chemical equation contains same number of atoms on both reactant and product side then this equation is known as balanced equation.

For example, H_3PO_4 + Ca(OH)_2 \rightarrow Ca(H_2PO_4)_2 + H_2O

Number of atoms on reactant side:

H = 5

P = 1

O = 6

Ca = 1

Number of atoms on product side:

H = 6

P = 2

O = 9

Ca = 1

In order to balance this equation, we will multiply H_3PO_4 by 2 on reactant side and we will multiply H_2O by 2 on product side. Hence, the balanced chemical equation is as follows.

2H_3PO_4 + Ca(OH)_2 \rightarrow Ca(H_2PO_4)_2 + 2H_2O

What amount if force need to be applied to a 20 kg bowling ball to give it an acceleration of 5m/s
balandron [24]

Answer:

100N

Explanation:

Given parameters:

Mass of the bowling ball  = 20kg

Acceleration  = 5m/s²

Unknown:

Amount of force applied  = ?

Solution:

To solve this problem, we apply newton's second law of motion.

    Force  = mass x acceleration

Now insert the parameters and solve;

   Force  = 20 x 5  = 100N
