Chemistry
1 answer:
Gnoma [55]3 years ago
4 0

Answer:

SiO2

Explanation:

  • Non-metals are elements that react by gaining electron(s) to attain a stable configuration and form an anion.
  • Unlike metals, non-metals are characterized by being poor conductors of heat and electricity.
  • In this case, the formula that contains non-metals is SiO2, it contains silicon and oxygen which are both non-metals.
  • The other choices contain a metal and a non-metal
  1. BaO - Contains Barium metal and Non-metal, Oxygen
  2. KI - Contains potassium metal and Non-metal, iodine
  3. NaBr - Contains sodium metal and non-metal, Bromine

Answer:

The correct answer is propane.

Explanation:

The movement of chemicals follows numerous standards, which indicate that each trailer must contain an ID number identifying the chemical being moved. This is necessary because before possible accidents and leaks we must know the measures to be taken before a leak.

Using the balanced equation below, how many moles of water can be produced when 4 grams of Hydrogen react? 2H2(g)+O2(g) —> 2H
gavmur [86]

Answer:

4 × 10 g

Explanation:

Step 1: Write the balanced equation

2 H₂(g) + O₂(g) ⇒ 2 H₂O(I)

Step 2: Calculate the moles corresponding to 4 g of H₂

The molar mass of H₂ is 2.02 g/mol.

4 g × 1 mol/2.02 g = 2 mol

Step 3: Calculate the moles of H₂O produced from 2 moles of H₂

The molar ratio of H₂ to H₂O is 2:2. The moles of H₂O produced are 2/2 × 2 mol = 2 mol.

Step 4: Calculate the mass corresponding to 2 moles of H₂O

The molar mass of H₂O is 18.02 g/mol.

2 mol × 18.02 g/mol = 4 × 10 g

Which term refers to the movement of materials through a cell membrane without using the cells energy
soldier1979 [14.2K]
<h3><u>Answer;</u></h3>

Passive transport

<h3><u>Explanation;</u></h3>
  • The movement of materials across the cell membrane without using cellular energy is called passive transport. On the other hand the energy-requiring movement of molecules across a membrane from a region of lower concentration to a region of higher concentration is called the active transport.
  • It includes processes such as osmosis. diffusion and facilitated diffusion.
  • Diffusion is the movement of dissolved molecules in a fluid or gas from a region of higher concentration to a region of lower concentration.
  • Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration.
  • Facilitated diffusion is a type of diffusion of molecules assisted by protein channels that pierce a cell membrane.
