Answer: M= 128 g/mol (Te is quite close)

Explanation: number of Oxygen moles is n = 8 g / 32 g/mol = 0,25 mol.

Because formula of oxide is MO, thus amount of metal is also 0,25 mol.

Because n = m/M , Molar mass of the metal M = m/n = 32 g /0.25 mol = 128 g/ mol

Answer:

Alloys and Composites

Explanation:

<u>Drill bits are made of alloys</u> because alloys are very much resistant to corrosion and are created when one or multiple metals are mixed with other elements that are non-metallic in nature. Due to their greater strength, they are used in the power drills in order to create borehole drills at the mining site. Borehole drilling is commonly done in order to understand the sub-surface strata before mining.

<u>The bodies along with the handles of power drills are constructed of composite insulators</u> because within the composites there is the absence of free electrons that has the ability to flow and produce electricity. So they are considered to be used as a good insulator.

What is the reading on your balance and that of your partner?what do these values represent?
never [62]
These values may represent the amount of pulling force that  we exert on each other or in other words exert forces on both parties.


The answer may differ as well but keep in mind the values should be equal.

Note:

The answer is not about helping each other or the "spring balance". We are not talking about the literal moral values instead we are talking about Chemistry and Science.

Write the balanced net ionic equation for the reaction that occur in the following case. Cr2(SO4)3(aq)+(NH4)2CO3(aq)→
solmaris [256]
Cr2(SO4)3(aq) + 3(NH4)2CO3(aq) → 3(NH4)2SO4(aq) + Cr2(CO3)3(s) 

<span>Ionic: 2Cr+3 + 3SO4^-2 + 6NH4+ + 3CO3^-2 ----> 6NH4+ + 3SO4^-2 + Cr2(CO3)3 (spectator ions are NH4+, SO4^-2) </span>

1. Describe how SHAPE can change during a collision. Be specific with your evidence and add detail to your answer.
a_sh-v [17]

Answer:

Hey

of course, the damage of a collision depends upon how fast to objects are moving at each other and how strong they are. If you have two tanks moving at each other 2 miles per hour it will be very little damage and the ->shape<- will not change much, maybe a dint or two. But if two balloons filled with water are moving at each other 5000 mph they will completely evoporate in a burst of light, and their ->shape<- will change very much. This is how shape and motion are related.

Hope it helped
