The molar mass of element X is 75 g/mol.

m(X₄O₆) = 59.4 g; mass of the compound

m(O) = 14.4 g; mass of oxygen in the compound

n(O) = 14.4 g ÷ 16 g/mol

n(O) = 0.9 mol; amount of oxygen in compound

m(X) = m(X₄O₆) - m(O)

m(X) = 59.4 g - 14.4 g

m(X) = 45.0 g; mass of element X

Ratio of the elements in the compound: n(X) : n(O) = 4 : 6.

n(X) = 0.9 mol × 4 / 6

n(X) = 0.6 mol; amount of element X in the compound

M(X) = m(X) ÷ n(X)

M(X) = 45.0 g ÷ 0.6 mol

The first location of chemical and mechanical digestion is the stomach. This statement is false.

Digestion is the breaking down of large insoluble food molecules into smaller water-soluble food molecules so that they can be absorbed into the aqueous plasma. In certain organisms, these small substances are absorbed from the small intestine into the bloodstream. Digestion is important for breaking down food into nutrients that the body uses for energy, growth, and cell repair that it needs to survive.

The digestive system has many forms. A basic distinction is made between internal and external digestion. External digestion evolved early in evolutionary history, and most fungi still rely on it. During this process, enzymes are secreted into the organism's environment, where organic substances are decomposed and some of the products diffuse back into the organism. Animals have a tube (alimentary canal) where internal digestion takes place. This is more efficient as more decomposition products can be trapped and the internal chemical environment can be more effectively controlled.

Between formic acid, HCO2H, and dichloroacetic acid, Cl2CHCO2H, dichloroacetic acid, Cl2CHCO2H is the stronger acid based on their pka.

Acids and bases can be classified into two: weak and strong.

A strong acid or a strong base completely dissociates in a solution while  weak acid or a weak base dissociates only partially.

Based on its dissociation constant, Ka, the larger the value of the Ka of an acid, the stronger it is.

On the other hand, the smaller the value of the logarithmic constant, pKa = - log Ka, the stronger the acid is.

Between formic acid, HCO2H, and dichloroacetic acid, Cl2CHCO2H, which has a pKa of 3.8 and 1.3, respectively, dichloroacetic acid, Cl2CHCO2H has smaller value of pKa.

On calculating using conversions, John can select either the package of wood with (a) 3 pieces of 2000mm each or the one with (d) 6 pieces of 100cm each.

On conversion of units from mm and cm to m:

1m = 100cm

1m = 1000mm

Therefore,

Since John requires 6m of wood to build a diving board, using unit conversions:

3 pieces of 2000mm each:

2000mm = 2m = 2m x 3 = 6m

4 pieces of 1.5 cm each:

1.5cm = 0.015m x 4 = 0.06m

6 pieces of 100 mm each:

100mm = 0.1m x 6 = 0.6m

6 pieces of 100 cm each:

100cm = 1m x 6 = 6m

8 pieces of 200 mm each:

200mm = 0.2m x 8 = 1.6m

Mass of kool aid required  is 3.42g to make 0.2 mole solution 1 liter

by the formula of molarity we know that molarity = mole/liter

We can enter those values into the equation to determine the necessary number of moles because we know that we want a 0.1Mole solution in 100 mL so by substituting the values 1/ 0.1= 0.01 moles.

We now know that there are 0.01 moles of Kool-Aid powder. Additionally, we are aware that this powder's chemical composition is c12 h22o11

By multiplying the atomic weight from the periodic table by the quantity of atoms in the compound, we may determine the molar weight of this powder. Let's calculate the powder's molar weight:

Find the carbon atomic weight

12 X 12 =144g

Then we have 22 H's, each having an atomic weight of 1.008g

22 X 11= 22g

And finally there are 11 O's, each with an atomic weight of 16g

16 X11 =176g

by adding the atomic weight of atoms 342.19g

now by finding the grams of kool compound  342.19 X 0.01mol = 3.42g.

Explanation:

a color change occurs cause when it Colides it mixes in with the other color and changes it completely

The correct answer is option C . Clue that a chemical reaction has taken place is not that the reactant is smaller.

Let's break down each of the options to understand why option c is incorrect:

a. A color change occurs: When a chemical reaction occurs, there may be a change in color. For example, when iron rusts, it changes from a metallic silver color to a reddish-brown color.

b. A flame occurs: Some chemical reactions produce heat, and if the reaction is exothermic enough, it can produce a flame. For instance, when wood burns, a flame is produced as a result of a chemical reaction between the wood and oxygen.

c. The reactant is smaller: This statement is incorrect. A chemical reaction does not necessarily mean that the reactant becomes smaller. Reactants can combine to form a larger product or they can rearrange to form different molecules without changing their size.

d. Bubbles form: When a gas is produced during a chemical reaction, bubbles may form. For example, when vinegar (acetic acid) reacts with baking soda (sodium bicarbonate), carbon dioxide gas is released, causing bubbles to form.

e. A solid forms: Some chemical reactions involve the formation of a solid. For instance, when a metal reacts with a non-metal, such as sodium reacting with chlorine to form sodium chloride, a solid salt is formed.

Thus, clues that a chemical reaction has taken place include a color change (option a), a flame (option b), bubbles forming (option d), and a solid forming (option e). The incorrect option is c, which states that the reactant becomes smaller.

When a substance moves down its concentration gradient, and energy is used to move another substance up its concentration gradient in the same direction is antiport secondary active transport

The primary active transport establishes the Na+ or H+ gradient. So to move substances against their concentration gradient, secondary transport uses energy derived from the hydrolysis of Adenosine triphosphate (ATP).

Secondary active transport is of two types - symport and antiport. When two or more substances move in the opposite direction using energy, it is termed an antiport. In this, one substance move inside, and another substance moves out of the cell. When two or more substance move in the same direction using energy is called symport. In this, either they are moving inside or out of the cell but move in the same direction.
