Exactly 10.0 L of air -25°C is heated to 100.0°C. What is the new volume if the pressure is kept constant?

Answer:

A person can identify their blood type at home using a rapid blood typing kit. Using the kit requires a person to pierce a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.

Explanation:

Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

Answer:

379.79 g of KCl

Explanation:

The balanced equation for the reaction is given below:

Cl₂ + 2KBr —> Br₂ + 2KCl

Next, we shall determine the mass of Cl₂ that reacted and the mass of KCl produced from the balanced equation. This can be obtained as follow:

Molar mass of Cl₂ = 70.90 g/mol

Mass of Cl₂ from the balanced equation = 1 × 70.90 = 70.90 g

Molar mass of KCl = 74.55 g/mol

Mass of KCl from the balanced equation = 2 × 74.55 = 149.1 g

SUMMARY:

From the balanced equation above,

70.90 g of Cl₂ reacted to produce 149.1 g of KCl.

Finally, we shall determine the mass of KCl produced by the reaction of 180.6 g of Cl₂. This can be obtained as follow:

From the balanced equation above,

70.90 g of Cl₂ reacted to produce 149.1 g of KCl.

Therefore, 180.6 g of Cl₂ will react to produce = (180.6 × 149.1)/70.90 = 379.79 g of KCl.

Thus, 379.79 g of KCl were obtained from the reaction.

Answer: dative covalent bond

Explanation: one hydrogen ion is transferred from HCl to the lone pair on NH3 . This particular hydrogen only has its nucleus transferred—its electrons remain with chlorine. So, the bond between this particular hydrogen atom and the central nitrogen is a dative covalent bond.

Answer: Most Hydrocarbon chains are found in petroleum, coal, and natural gas. First of all, a hydrocarbon chain is a molecule that consist of entirely hydrogen and carbon.

Explanation: There are many types of hydrocarbon chains, which can be found in alkanes, alkynes, arenes, alkenes, and cycloalkanes. Natural rubber for instance is a hydrocarbon that primarily consists of alternating single and double bonded carbons.

Answer:

B. 0.35mol KClO3

Explanation:

The balanced equation in this question is given as follows:

2KClO3 → 2KCl + 3O2

Based on the chemical reaction;

2 moles of KClO3 decomposes into 3 moles of O2

If 0.525 moles of O2 are produced, then:

= 0.525 × 2/3

= 1.05/3

= 0.35mol of KClO3 is decomposed.

Answer: [tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]

Explanation:

Equilibrium constant is defined as the ratio of pressure of products to the pressuure of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_p[/tex]  

For the given chemical reaction:

[tex]P_4(s)+6Cl_2(g)\rightarrow 4PCl_3(l)[/tex]

The expression for [tex]K_p[/tex] in terms of gaseous is written as:

[tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]

Answer:

Al(OH)- 4,

Explanation:

NaOH  added to 0.010 M Al3+

The predominant species at equilibrium will be = Al(OH)- 4,  and this because sodium hydroxide ( NaOH ) is a base will readily form a stable complex ion with aluminum ion like ( Al( OH ) - 4 . also the higher the Kf value the more stable the complex ion becomes and the more soluble  Al(OH)3 becomes

hence the predominant species at equilibrium is : Al(OH)- 4,
