Answer:
976.8 g
Explanation:
C₅H₁₂ + 8O₂ → 5CO₂ + 6H₂0 ------------(1)
number of moles of reaction 1 can be shown as;
1 : 8 → 5 : 6
thus, 5 moles of CO₂ will form from the combustion of 1 mole of C₅H₁₂
molecular weight of CO₂ = 44 g/mol
molecular weight of C₅H₁₂ = 72 g/mol
mass of C₅H₁₂ = 320 g
number of moles of C₅H₁₂ = mass ÷ molecular weight = 320 / 72 = 4.44 moles
thus, number of moles of CO₂ formed = 5 * 4.44 = 22.2 moles
mass of CO₂ formed = 22.2* 44 = 976.8 g
Answer: You will need mountaineering equipment such as ice axes and crampons, clothing such as gloves and headwear, and supplies such as food, a stove to thaw water and the food, and first aid materials.
Explanation: Please mark as brainliest lol!
A) Metallurgy
I hope this one is the correct one , its been a while sine I did history .
Good Luck!
Of all the elements, fluorine is the most electronegative and reactive. Fluorine is a diatomic, pale yellow, extremely corrosive, combustible gas with a strong smell. The lightest halogen is it. It produces oxygen and the incredibly corrosive hydrofluoric acid when it combines strongly with water.
<h3>The properties of the oxide and the fluoride?</h3>
- 1. A mixture of oxygen fluorides with an atomic ratio OF in the range of 1.1-2.04 is generated when fluorine and oxygen mixes are easily circulated through a silent electric discharge.
- Depending on where you reside in the UK, fluoride is a naturally occurring mineral that is present in water in variable concentrations. It is added to many types of toothpaste and, in some locations, the water supply through a procedure known as fluoridation because it can aid in the prevention of tooth decay.
- Fluoride stops tooth decay by strengthening the enamel's resistance to acid attack. They also quicken the process of good minerals accumulating in the enamel, further delaying the onset of deterioration. Studies also suggest that fluoride may occasionally be able to stop tooth decay that has already begun.
