Answer:

Base

Explanation:

Acid + Base ⇒ Salt + Water (Neutralization Reaction)

So the substances forming salt and water must be acid and base.

Since HCl is acid so the Metal Oxide would be the base.

The answer to your question is option b, a base. This is because the question clearly tells you that one reactant is an acid. Then, it tells you that an acid plus something gives you a salt and water, as products

From background knowledge, we know that a base plus acid gives you a salt and water. The hydroxide ions from the base neutralise the hydrogen ions from the acid, which gives you water ( as it has a pH of 7).

Therefore, your answer is b, a base

Answer:

Try using Ptable or chemicalaid

Explanation:

Ptable is a great website that shows you a dynamic periodic table. It can show you which elements are Halogens, Alkali metals, transition metals, noble gases, and etc!

Chemicalaid is a nice website to find out more information about specific elements, it also lists every element on the periodic table.

frutty [35]

Answer:

A monosaccharide that contains 4 carbon atoms, one of which is in an aldehyde group, is classified as an aldotetrose.

Explanation:

A tetrose is a monosaccharide with 4 carbon atoms.

They have either an aldehyde functional group in position 1 (aldotetroses).

or a ketone functional group in position 2 (ketotetroses).

So, A monosaccharide that contains 4 carbon atoms, one of which is in an aldehyde group, is classified as an aldotetrose.

How many grams of N2 are required to produce 240.0g NH3?
7nadin3 [17]
Balanced equation: N2 + 3H2 ==> 2NH3
moles of NH3 in 240.0 g NH3: 240.0 g x 1 mol/17 g = 14.1 moles
moles N2 needed: 14.1 moles NH3 x 1 mole N2/2 moles NH3 = 7.05 moles N2 needed
grams N2 needed: 7.05 moles x 28 g/mole = 197.4 grams needed :)

A hypothetical covalent molecule, X–Y, has a dipole moment of 1.93 1.93 D and a bond length of 109 pm. 109 pm. Calculate the par
Gnesinka [82]

Answer:

q= 110.5 ke

Explanation:

Dipole moment is the product of the separation of the ends of a dipole and the magnitude of the charges.

μ = q * d

μ= Dipole moment (1.93 D)

q= partial charge on each pole

d= separation between the poles(109 pm).

e= electronic charge ( 1.60217662 × 10⁻¹⁹ coulombs)

So,

q= \frac{1.93}{109 * 10^{-12} } coulombs

q = \frac{1.93}{109 * 10^{-12} *  1.60217662 * 10^{-19} } e

q = 1.105 * 10⁵ e

q= 110.5 ke
