How many reactants and products are present in a double-replacement reaction?

Biology

Answer : The correct option is, two reactants and two products.

Explanation :

Double replacement reaction : It is a type of chemical reaction in which a positive cation and a negative anion of two reactants exchange their places to form two new products.

It is represented as,

XY+AB\rightarrow XB+AY

(X and A are the cations, Y and B are the anions)

For example : Barium chloride react with magnesium sulfate to give barium sulfate and magnesium chloride as a product.

The balanced chemical reaction will be:

BaCl_2+MgSO_4\rightarrow MgCl_2+BaSO_4

From this we conclude that, there are two reactants and two products are present in a double-replacement reaction.

Hence, the correct option is, two reactants and two products.

Oksana_A [137]

volcanic activity

Answer: Option D.

<u>Explanation:</u>

Volcanoes are regular along tectonic plate boundaries where oceanic plates sink underneath different plates. As a plate sinks profound into a subduction zone, it warms and starts to soften, shaping magma.

Volcanoes are likewise basic along structural limits where plates pull separated, permitting magma to ascend from the mantle.Volcanoes are generally basic in these geographically dynamic limits. The two sorts of plate boundaries that are well on the way to create volcanic movement are divergent plate boundaries and convergent plate boundaries.

When a cell prepares to divide, the chromatin condenses into rod-shaped structures called?
MA_775_DIABLO [31]

Answer:

Chromosome

Explanation:

As the cells prepare for cell division, several events occur. During the prophase of mitosis, the thin threads of chromatin are condensed into rod-shaped visible structures. The process of compaction of chromatin gives rise to chromosomes. Chromosomes are rod-shaped structures made up of DNA and packaging proteins. Since DNA replication has already occurred during the S phase of interphase, each chromosome has two sister chromatids.

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers;
kipiarov [429]

Answer:

Answer is 3/16.

Explanation:

If the F1 progeny has red axial flowers this shows us that red and axial genes are dominant. If we say that R is for red dominant gene, r is for white recessive gene.

If we say A is axial dominant gene, a is for terminal recessive gene.

All F1 progeny has AaRr phenotype.

When we cross them, Aa x Aa  can have AA Aa Aa aa

When Rr x Rr crossed, RR Rr Rr rr

The F2 progeny can have white axial flowers by having a and R in the phenotype with the possibility having aa= 1/4 , R in the phenotype , the possibility is 3/4.

1/4 x 3/4 = 3/16 in all F2 progeny
