The wavelength will go down if the velocity of the wave is constant. the formula is w=v/f
Answer:
<em><u>transmission</u></em>
Explanation:
When light waves passes straight through an object, it is called <em><u>transmission</u></em>.
Its me again XD
C, to make sure the design works as expected.
A prototype is first, typical model of the said product. Hope this helps!
The Rivergate because you are basing the distance off of there
Answer:
The answer to your question is 58.7 g of Ca(OH)₂
Explanation:
Data
mass of Ca(OH)₂ = ?
mass of HNO₃ = 100 g
Process
1.- Write the balanced chemical reaction
Ca(OH)₂ + 2HNO₃ ⇒ Ca(NO₃)₂ + 2H₂O
2.- Calculate the molar mass of the reactants
Ca(OH)₂ = 40 + 32 + 2 = 74 g
HNO₃ = 1 + 14 + 48 = 63 g
3.- Use proportions to calculate the mass of Ca(OH)₂
74 g of Ca(OH)₂ ----------------- 2(63) g of HNO₃
x ----------------- 100 g of HNO₃
x = (100 x 74) / 2(63)
x = 7400 / 126
x = 58.7 g
