Answer:
A polar bond is one where the charge distribution between the two atoms in the bond is unequal. A polar molecule is one where the charge distribution around the molecule is not symmetric. It results from having polar bonds and also a molecular structure where the bond polarities do not cancel.
Explanation:
Answer:
I think it's B
Explanation:
B is talking about the bees helping the flowers, so that isn't helping the bees but the flowers instead
Answer:
the only remote information i could find about this element was sodium
dicyanidoaurate(I)
sodium dicyanoaurate(1-)
Na[Au(CN)2]
sodium dicyanidoaurate(1-)
but as you see these go towards Na[Au(CN)2] not Na[Au(CN)4], so I will leave the rest up to you.
Have a good day.

that is the website i found that off of

this one tells you the element names.
Answer:
4510 J
Explanation:
To calculate the energy of the water, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy/heat (J)
-----> m = mass (g)
-----> c = specific heat capacity (J/g°C)
-----> ΔT = change in temperature (°C)
First, you need to determine the mass of the water. To do this, you need to multiply the given volume by the density of water (1.00 g/mL).
100.0 mL H₂O 1.00 g
------------------------ x ------------ = 100.0 g H₂O
1 mL
Now, you can plug the given values into the equation and solve for "Q" (Q = ). The final answer should have 3 significant figures to match the given values with the lowest number of sig figs.
Q = ? J c = 4.18 J/g°C
m = 100.0 g ΔT = 32.0 °C - 21.2 °C = 10.8 °C
Q = mcΔT
Q = (100.0 g)(4.18 J/g°C)(10.8 °C)
Q = 4510 J
Explanation:
The temperature of the stratosphere (which contains Earth's ozone layer) actually increases in temperature as you move higher, so the statement is false. This phenomenon is caused by the absorption of solar radiation by ozone molecules concentrated in the upper stratosphere.
