1 calorie is equal to 4.184 Joules.
25/2 and 96/X
CROSS MULTIPLY.
2x=2,400.
divide by 2.
x=1,200.
you take the GIVEN MASS of an element, and you put it on top, the coefficient is what it’s over. i believe this is right
Answer:
53,600 centimeters
Explain; kilo=1000
hecta=100
deca=10
unite=0(meter,leter,
deci=0.1
centi=0.01
milli=0.001
0.536 kilo is opposite of 536,000 milli

Answer:
Well a human bein is a complex organism with pain and emotion.
There is a very very complex brain that recives and sends sis also faster than the eye can see.
Thats why when you touch a hot surface a lighting fast signal is sent from the hand to the brain and the brain sends a signal back to the hand to tell it what to do and this all happens a faster than a second.
A human is made out of millions, billions, trillions, and quadrillions if cells working together to perform special tasks like eating, walking, and talking.
The theoretical molar yield of lead (II) chloride will be 9 moles.
<h3>Stoichiometric calculation</h3>
First, we need to look at the equation of the reaction:
From the equation, the 1 mole of Pb2+ ion requires 2 moles of Cl- ion in order to produce 1 mole of lead (II) chloride.
Thus, with 18 moles Cl- ions, 9 moles of Pb2+ would be needed, instead of 12 moles. Pb2+ is simply in excess while Cl- can be said to be limiting.
Therefore, Cl- will determine how much of lead (II) chloride that will be produced. The ratio is 2 moles of Cl- to 1 mole of lead (II) chloride.
With 18 moles Cl-, 9 moles of lead (II) chloride will, thus, be produced.
