Answer:
Q = 31798.4J = 31.79kJ
Explanation:
Heat energy (Q) = ?
Mass (m) = 152g
T1 = 24°C
T2 = 74°C
Specific heat capacity of water (c) = 4.184J/g°C
Q = Mc∇T
Q = 152 * 4.184 * (74 - 24)
Q = 635.968 * 50
Q = 31798.4J
Q = 31.79kJ
Heat required is 31.79kJ
Answer:
Therefore, when the kinetic energy increases by four times, then the moment will increase by two times.
Answer:
12.11.
Explanation:
∵ pOH = - log[OH⁻]
<em>∴ pOH</em> = - log(1.3 x 10⁻²) = <em>1.886.</em>
∵ pH + pOH = 14.
<em>∴ pH = 14 - pOH</em> = 14 - 1.886 = <em>12.11.</em>
You take the mass of carbon dioxide, 56.8g, divide by its molar mass, 44.01g/mol, to produce the moles of carbon dioxide. This is multiplied by the molar ratio of butane/CO2, (2/8) = 1/4, which gives the moles of butane required to produce the carbon dioxide.
Answer:
Law of cross-cutting relationships
Explanation:
This interpretation is based on the law of cross - cutting relationships.
This law states that "faults and fractures that cuts through a rock are younger than the rocks they cut through".
- In a sequence of strata, the strata that are not cut through by these features are younger than the cross -cutting features.
- The igneous intrusion is younger since it cuts through the rock layers.
