Chemistry
1 answer:
Volgvan3 years ago
5 0

Answer:

It ionizes completely in solution

Explanation:

The main characteristics of a strong acid is that it ionizes completely in solution. A strong acid will produce hydroxonium ions in solution.

A weak acid does not ionize completely in solution. Their ionization is very small and most times, the exists in equilibrium phase with the product formed.

A weak base also ionizes partially in solution.

A weak acid does not ionize completely in a given solution and it exists in equilibrium with the product.

The actions of strong acids are usually fast.

What is the mass in grams of 5.40 moles of lithium.
Maslowich
You would use the formula:

n = \frac{m}{M}

Where m is the mass, and M is molar mass (the periodic table would be used for this)

In this case, we need to rearrange the formula to find m

m = nM
    = 5.40 x 6.941
    = 37.5g

Hope this helped! Ask me if there's any part of the working you don't understand :)

Ways to reduce your carbon footprint.
sergejj [24]

Answer:

  • Avoid driving as much as you can
  • Avoid plastic in general (Plastic is usually not recycled, despite what people say. It ends up in landfills, the ocean, or it is burned)
  • Don't buy fast fashion (Clothes that are made in bulk by factories usually in Bangladesh. They are trendy but bad for the environment. Instead, shop at thrift stores.)
  • Don't waste food! Stop throwing out those leftovers, and make sure you eat everything on your plate.
  • Try to switch to renewable energy. (Use solar panels or find lights that conserve energy. Also, these options most likely cost less :)
  • Try to cut back on your meat intake. (I am a pescatarian who loves meat. I started this diet in 4th or 5th grade because it was a dare. I know, it was a crazy dare, but hey I don't back down! It's been about 5 years now and I'm still going strong. If me - a meat lover - can do it, you can to :)

I need help understanding polyatomic ions
Vinvika [58]
A polyatomic ion, also known as a molecular ion, is a charged chemical species (ion) composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit. The prefix poly- means "many," in Greek, but even ions of two atoms are commonly referred to as polyatomic

a sample of gold required 2.1200j of heat to melt it from room temperature, 22.0 degrees celsius to its melting point, 1064.4 de
ElenaW [278]

Mass of Gold = 267.165 ×  0.01552494829

⇒ 4.1477228099

The amount of heat(q) required to raise m grams of a substance-specific C from T1 to T2 is given by

q=m C (T2-T1) ........1

Given : q= 2.1200 J

the initial temperature of gold, T1 = 22.0Celcius

the final temperature of gold, T2 = 1064.4Celcius

specific heat of gold = 0.131

putting values in eq 1:

⇒ 2.1200 = m × 0.131 × (1064.4-22)

⇒ 2.1200 = m × 0.131 × 1042.4

⇒ 2.1200 / 136.5544

⇒ 0.01552494829

Since 1g= 0.01552494829 Pounds

Mass of Gold = 267.165 ×  0.01552494829

⇒ 4.1477228099
