Vinegar is a liquid consisting of about 5–20% acetic acid(CH3COOH),

Sodium hydroxide is a strong base. In concentrated form its pH can go up to somewhere in the region of 13-14

The salts produced by the action of ammonia on acids are known as the ammonium salts and all contain the ammoniumion (NH4+). Although ammonia is well known as a weak base, it can also act as an extremely weak acid.

Water acts as a base (accepts H+) when it reacts with a stronger acid, say hydrochloric acid. If the medium is water, water, having a pH of 7, is considered neutral. If the medium is ethanol (or any other solvent), water can be acidic, neutral or basic

The reaction between calcium carbonate (CaCO3) and HCl produces calcium chloride (CaCl2), carbon dioxide (CO2), and water (H2O).

Lisa [10]

When the hydrogen chloride concentration doubles, the number of collisions between the reactants becomes increased, which causes the rate of the forward reaction to be faster.

<h3>What is the rate of a reaction?</h3>

The rate of a reaction is how fast a chemical reaction occurs i.e. the conversion of reactants to products.

The rate of a chemical reaction can be influenced by certain factors including the concentration of reactants.

The more the concentration of a reactant, the more the collision between the reactants and hence, the faster the reaction will proceed.

Therefore, when the hydrogen chloride concentration doubles, the number of collisions between the reactants becomes increased, which causes the rate of the forward reaction to be faster

Several narrow linear bloodstain patterns are found on a wall adjacent to one where a body was found the droplets were elongated

ryzh [129]

The correct answer is letter D. A knife would most likely cause this blood spatter pattern because of the direction of the force that was inhibited on the weapon and the victim. The direction of the spatter will also depend on the body part that was hit by the weapon.

5 g of gold and 25 g of silver are mixed to form a single-phase ideal solid solution. (a) how many moles of solution are there?

worty [1.4K]

Mole fraction for silver= 0.2317643/0.3079193

= 0.7526787

Mole fraction for gold=0.076155/0.3079193

=0.2473212

What is Molar Fraction?

The mole fraction is the product of the number of molecules of a specific component in a mixture and its total molecular weight. It serves as a means of indicating how concentrated a solution is.

It is a unit of concentration, defined as the product of the moles of a component and the moles of the entire solution. When all the parts of a solution are summed up, their mole fraction equals 1.

molar mass of silver = 107.8682g/mol

Molar mass of gold= 196.96657g/mol

Therefore mole = mass/molar mass

For silver: 25g/107.8682g/mol = 0.2317643mol

For gold: 15g/196.96657g/mol= 0.076155mol

Total number of mole= 0.2317643+0.076155

= 0.30791193mol

Mole fraction for silver= 0.2317643/0.3079193

= 0.7526787

Mole fraction for gold=0.076155/0.3079193

=0.2473212

Put the following elements into five pairs of elements that have similar chemical reactivity: F, Sr, P, Ca, O, Br, Rb, Sb, Li, S

kirill115 [55]

Explanation:

Given elements:

F, Sr, P, Ca, O, Br, Rb, Sb, Li, S

Elements with the same chemical reactivity will belong to the same group on the periodic table. This implies that elements in the same column will have the same reactivity;

Li and Rb are both alkali metals in group 1

Ca and Sr are both alkali earth metals in group 2

F and Br are halogens in group 7

O and S are group 6 elements

P and Sb are both in group 5 on the periodic table

So these groupings show elements with the same chemical properties.
