The answer is B, maltose.

Maltose is a disaccharide, composed of two monosaccharide. It can be broken down by amylase, a enzyme, from starch, a polysaccharide. Maltose is also important in beer, even though it is decomposed into ethanol by yeast.

Maltose is only only disaccharide that matches the description so the answer is B.

At a given temperature, 4.06 atm of H2 and 3.5 atm of Cl2 are mixed and allowed to come to equilibrium. The equilibrium pressure

Llana [10]

<u>Answer:</u> The value of $K_p$ for the given chemical reaction is 0.1415

<u>Explanation:</u>

Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of the products and the reactants each raised to the power their stoichiometric ratios. It is expressed as $K_p$

For a general chemical reaction:

$aA+bB\rightarrow cC+dD$

The expression for $K_p$ is written as:

$K_p=\frac{p_{C}^cp_{D}^d}{p_{A}^ap_{B}^b}$

For the given chemical equation:

$H_2(g)+Cl_2(g)\rightleftharpoons 2HCl(g)$

The expression for $K_p$ for the following equation is:

$K_p=\frac{(p_{HCl})^2}{(p_{H_2)}(p_{Cl_2})}$

We are given:

$p_{HCl}=1.418atm\\p_{H_2}=4.06atm\\p_{Cl_2}=3.5atm$

Putting values in above equation, we get:

$K_p=\frac{(1.418)^2}{(4.06)\times (3.5)}\\\\K_p=0.1415$

The value of $K_p$ for the given chemical reaction is 0.1415

You have a substance and begin a set of experiments in which you break it down into other substances through chemical reactions.

a_sh-v [17]

They're elements. Elements are the simplest form of any substance that cannot be broken down by any chemical methods, including electrolysis or even heat. Examples include oxygen, hydrogen etc.

29 Positrons and beta particles have(1) the same charge and the same mass

Rama09 [41]

Usually the beta particles are electrons with negative charge. And positrons are with positive charge. So they have the same mass and different charges. The answer is (3).
