<h2><u><em>Answer:</em></u></h2><h2><u><em>the one below is basically noble gas</em></u></h2><h2><u><em>For example, helium, neon, and argon are some of the individual atoms which are also known as noble gases and have very low chemical reactivity. ... Liquids are made of vibrating particles of matter that are held together by molecular bonds (e.g. atoms). The most common liquid you'll find is water</em></u></h2><h2><u><em>An element is a pure substance as well, because if we fill up a balloon with just helium gas, it will only contain helium atoms. On the periodic table of elements, helium is element number 2 , and so that should tell you that it's an element of course...</em></u></h2><h2><u><em>why didn't the skeleton cross the street?</em></u></h2><h2><em><u>"I dunno why"</u></em></h2><h2><em><u>because he didn't have the guts to do it</u></em></h2><h2><em><u>hahahah</u></em></h2><h2><em><u>mark brainliest plzs</u></em></h2>

How many milliliters of a 0.285 M HCl solution are needed to neutralize 249 mL of a 0.0443 M Ba(OH)2 solution?

meriva

Answer:

$\large \boxed{\text{77.4 mL}}$

Explanation:

Ba(OH)₂ + 2HCl ⟶ BaCl₂ + H₂O

V/mL: 249

c/mol·L⁻¹: 0.0443 0.285

1. Calculate the moles of Ba(OH)₂

$\text{Moles of Ba(OH)$_{2}$} = \text{0.249 L Ba(OH)}_{2} \times \dfrac{\text{0.0443 mol Ba(OH)}_{2}}{\text{1 L Ba(OH)$_{2}$}} = \text{0.011 03 mol Ba(OH)}_{2}$

2. Calculate the moles of HCl

The molar ratio is 2 mol HCl:1 mol Ba(OH)₂

$\text{Moles of HCl} = \text{0.011 03 mol Ba(OH)}_{2} \times \dfrac{\text{2 mol HCl}}{\text{1 mol Ba(OH)}_{2}} = \text{0.022 06 mol HCl}$

3. Calculate the volume of HCl

$V_{\text{HCl}} = \text{0.022 06 mol HCl} \times \dfrac{\text{1 L HCl}}{\text{0.285 mol HCl}} = \text{0.0774 L HCl} = \textbf{77.4 mL HCl}\\\\\text{You must add $\large \boxed{\textbf{77.4 mL}}$ of HCl.}$

Calculate the number of atoms in 2.0g of hydrogen atoms?

Jobisdone [24]

First you calculate how many moles there are in 2.0 grams of hydrogen (H2) atoms.
Hydrogen has a relative atomic mass (RAM) of 1 g/mol, but there are 2 hydrogen atoms: 1 x 2 = 2 g/mol

To work out how many moles there are,
use the formula: n(moles) = mass ÷ molar mass
n(moles) = 2 grams ÷ 2 g/mol = 1 mol

Then use Avogadro's Constant : 6.023 x 10^23
= 1 x 6.023 x 10^23
= 6.023 x 10^23

Final step is to multiply it by the number of atoms, in this case there are 2.
= 6.023 x 10^23 x 2
= 12.046 x 10^23
= 1.205 x 10^24

that ^ should be your final answer

have a great day :)
