Answer:
Number of moles of oxygen used=13.5moles
Explanation:
To know the number of moles of oxygen used, first calculate the molar mass of water.
H2O=(2*1)+(1*16)
=2+16
18g/mol of H2O
The moles of H2O is 7.6 moles
So first, find the molar mass of oxygen
O2=2*16
=32g/mol
Then, number of moles of oxygen is equal to molar mass of oxygen divide by the molar mass of water times the number of moles of water
No. moles of O2=[32g/mol]/[18g/mol] *7.6moles
Moles of O2=1.778*7.6moles
No.moles of O2=13.5 moles
Therefore, the number of moles of oxygen used was 13.5moles
Answer:
energetic particles
Explanation:
"Pioneer 10" was the first aircraft to complete a mission to<em> Jupiter.</em> It was launched on<em> March 2, 1972</em> and eventually became the first spacecraft to travel across the asteroid belt.
"Pioneer 11" was considered to be the <em>second spacecraft </em>to have studied the outer solar system after the launch of Pioneer 10. It focused on studying the <em>asteroid belt, solar winds, cosmic ray</em>s and the condition surrounding Saturn and Jupiter.
Jupiter has a <em>magnetosphere</em> that constantly ejects energetic particles. It produces a lethal dose of radiation that is harmful, especially to humans. This damaged both Pioneer 10 and 11. However, Pioneer 10 is said to have been able to communicate with Earth for 30 years despite receiving damages.
So, this explains the answer.
Litmus paper is an indicator that changes color to identify the acidity or basicity of a certain substance. This changes color from blue to red for acids. Since given the same concentration of the compounds, the number of H⁺ in H₂SO₄ is approximately twice that of HCl.
Therefore, fewer drops of H₂SO₄ will be required in order to change the color of the litmus paper.
Answer:
Hi i got , B. He is right, because there will be more successful collisions between reactants in the 1.0 M solutions.
