Answer:
a) 35°C, the temperature on a hot summer day
b) -11.11°C, the temperature on a cold winter day
c) a 38.88°C fever
d) a furnace operating at 1011.11°C
e) 523.67°F ( theoretically the lowest attainable temperature )
Explanation:
- °C = ( °F - 32 ) / 1.8
- °F = ( 1.8 * °C ) +32
a) 95°F ⇒ °C = ( 95 - 32 ) / 1.8 = 35°C
b) 12°F ⇒ °C = ( 12 - 32 ) / 1.8 = -11.11°C
c) 102°F ⇒ °C = ( 102 -32 ) / 1.8 = 38.88°C
d) 1852°F ⇒ °C = ( 1852 -32 ) / 1.8 = 1011.11°C
e) 273.15°C ⇒ °F = ( 1.8 * 273.15 ) + 32 = 523.67°F
Answer:
0.043 M
Explanation:
The reaction that takes place is:
- Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O
First we <u>calculate how many HCl moles reacted</u>, using the <em>given concentration and volume required to reach the equivalence point</em>:
- 0.029 M HCl * 37.3 mL = 1.0817 mmol HCl = 1.0817 mmol H⁺
As 1 mol of H⁺ reacts with 1 mol of OH⁻, in the 25.0 mL of the Ca(OH)₂ sample there are 1.0817 mmoles of OH⁻.
With that in mind we can <u>calculate the hydroxide ion concentration in the original sample solution</u>, using <em>the calculated number of moles and given volume</em>:
- 1.0817 mmol OH⁻ / 25.0 mL = 0.043 M
Answer:
double replacement reaction or double displacement reaction,
Explanation:
double replacement reaction, double displacement reaction, is a chemical process involving the exchange of bonds between two non-reacting chemical species which results in the creation of products with similar or identical bonding affiliations
Classically, these reactions result in the precipitation of one product.
in thía case it is AgCl
The density of ice does not affect the melting rate. But, adding an object does affect the melt rate. The reason this is is because when there is an object, there is less to melt. Hence, affecting the melting rate.

Explanation:
1 mole of a substance contains Avagadro’s number of particles,
i.e. 6.023*10^23
By unitary method,
5 moles of oxygen contains 5 times the Avagadro’s number of particles
i.e. 5* (6.023*10^23) = 3.0115*10^24 number of particles.
Now, the further answer depends on what particles the question concentrates on.
If number of atoms are asked , the above answer must be multiplied by 2, because oxygen is a diatomic gas and each atom contributes to be a particle.
therefore, 5 moles of oxygen has 6.023*10^24 atoms.
If number of molecules asked, the above answer is directly written...
