The definition for "What do you call two or more atoms bonded together" is a compound. Think of water. Water is called H20. Water is made of 2 hydrogen atoms and 1 oxygen atom. That is to atoms bonded together to make a compound which is water. Hope I helped
The correct answer is the combination of a metal with another element.
An alloy is a combination of two or more metallic elements to make a stronger material. For instance, there are bronze alloys, brass alloys, and coin alloys.
We can confirm that an alloy is a combination of one metal with another metal because stainless steel is made of an iron and chromium alloy (iron is a metal; chromium is also a metal). Therefore, we can confirm that option C is the best choice.
Answer:
1008.0 kJ.
Explanation:
- Firstly, we need to calculate the no. of moles of 88.0 g of propane:
<em>n = mass/molar mass </em>= (88.0 g)(/(44.0 g/mol) = <em>2.0 mol.</em>
∴ The combustion of 2.0 moles of propane produces 4032.0 kJ.
<em><u>Using cross multiplication: </u></em>
The combustion of 2.0 moles of propane produces → 4032.0 kJ.
The combustion of 0.5 moles of propane produces → ??? kJ.
<em>∴ The amount of heat released for the combustion of 0.5 moles of propane </em>= (4032.0 kJ)(0.5 mol)/(2.0 mol) = <em>1008.0 kJ.</em>
Impartial is the word that you want to use
Answer:
<em>True</em>
Explanation:
Arsenic is an element that has similar behavior to metal, it is toxic to humans. It can be produced by some human activities but it is also available in nature in its organic or inorganic form, this last one being more toxic.
Organic arsenic can be found especially in sea-living organisms.
Inorganic arsenic can be found in the earth's crust and it can affect the acidity levels (PH) of the soil.
