What is the missing value​

Chemistry
2 answers:
Korvikt [17]2 years ago

Answer:

72

Explanation:

The pattern here may be hard to find at first, but it's this: the number in the middle of the triangle = (number at lower left corner of triangle x number at upper vertex of triangle) + (number at upper vertex of triangle x number at lower right corner of triangle).

Thus, for the missing value...

Missing value = (3x8) + (8x6) = 24+48 = 72.

Could you tell me what concept in chemistry relates to this? I'm interested.

Also check out stylesben's answer. Seems like there's several ways of doing this.

There is a container on the lab bench containing some unknown chemical. what should you do?
iragen [17]

Ask your lab manager for instructions. If you happen to be the lab manager, take out the container (making a note of where it is), find the culprit, and try to figure out what might be in the beaker so you can know how to properly dispose of it.

Proper safety measures should be followed.

<h2>What are the safety measures in chemistry lab?</h2>

In the lab, always use the proper eye protection, such as chemical splash goggles. When handling hazardous items, put on the disposable gloves that the laboratory has given. Before leaving the lab, take the gloves off. Put on a full-length, long-sleeved lab coat (apron) or apron that can withstand chemicals.

Explain what is meant by Pleistocene ice age
makkiz [27]

By Pleistocene ice age is meant the glacial periods that appeared in the Pleistocene. The Pleistocene is the first epoch of the Quaternary. It is an epoch when there was a so called ''ice age'' on the Earth, or rather a glacial period. During this ice age the planet had much lower temperatures on a global scale. The climate was also much drier. Lot of ocean water was frozen in the ice sheets that were stretching deep into the North American and Eurasian continents, which resulted in much lower sea levels that today as well. The places further north than 40 degrees of latitude were almost exclusively covered with ice, so life was almost impossible apart from some coastline places.

Metals (M) in group 2 of the periodic table form ionic bonds
egoroff_w [7]

Answer:

16

Explanation:

Group two elements are alkaline earth metal.

All these have two valance electrons. In order to achieve noble gas configuration it loses its two valance and get complete octet.

Reaction with group 16.

Reaction with oxygen,

They react with oxygen and form oxide.

2Ba   +   O₂   →    2BaO

2Mg  +   O₂   →    2MgO

2Ca +   O₂   →    2CaO

this oxide form hydroxide when react with water,

BaO  + H₂O   →  Ba(OH)₂

MgO  + H₂O   →  Mg(OH)₂

CaO  + H₂O   →  Ca(OH)₂

With sulfur,

Mg + S   →  MgS

Ca + S   →  CaS

Ba + S   →  BaS

I'm looking at the barometer in my lab as I type this question. It says the pressure is 968 torr. What is this pressure expresse
Ksenya-84 [330]

Answer:

1.27 atm.

Explanation:

The following data were obtained from the question:

Pressure (P) in torr = 968 torr

Pressure (P) in atm =...?

Thus, we can convert from torr to atm by doing the following:

Recall:

760 torr = 1 atm

Therefore,

968 torr = 968/760 = 1.27 atm

Therefore, 968 torr is equivalent to 1.27 atm.
