Answer: 0.123 M
Explanation:
According to the neutralization law:
where,
= molarity of 
solution = ?
= volume of solution = 15.00 ml
= molarity of 
solution = 0.100 M
= volume of solution = 18.44 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of the unknown HBr solution is 0.123 M
The heat needed to raise the temperature of 50g of substance by 15 c is calculated as follows
Heat = mc delta T
m= mass (50g)
c= specific heat capacity (0.92)
delta T= change in temperature( 15 c)
heat is therefore= 50 x 0.92 x 15 = 690
Nb: my answer has no units since the given specific heat capacity has no units
Answer:
This depict that the growth of the new plant has taken place due to asexual form of reproduction.
Explanation:
A procedure in which new offspring is generated from a single parent without involving sex cells or gametes is known as asexual reproduction. One of the asexual forms of reproduction in plants is the artificial propagation of plants. The three general procedures of artificial propagation of plants are layering, cuttings, and grafting.
In cutting, a novel plant is developed by incising a small section of a plant that can be anything comprising bud on it. This section of the plant is then watered and grown into soil, and after some days a new plant begins to grow.
Answer:
it depends on how you use action Because action means you are doing something and maybe action like reaction or something like a feeling if a bomb occurs that is the action.
