Answer:

D. Hydrogen has a valence of 1 and oxygen has a valence of 6

Explanation:

Electrons present in the outer most shell of an atom is known as valence electrons.

Here oxygen has 6 valence electrons in its outermost shell while hydrogen has only one valence shell in its outermost shell

So here if hydrogen share its one electron with oxygen then its electron configuration becomes stable and if oxygen share its two electrons of the shell with two different hydrogen atoms then this will stable the electron configuration of oxygen.

So in this way hydrogen and oxygen forms bonds with each other and its bond sharing electrons will form bond.

so here correct answer will be

D. Hydrogen has a valence of 1 and oxygen has a valence of 6

evablogger [386]

Given the time, the final velocity and the acceleration, we can calculate the initial velocity using the kinematic equation A:

$v = v_o + a \Delta t$

A skateboarder flies horizontally off a cement planter. After a time of 3 seconds (Δt), he lands with a final velocity (v) of −4.5 m/s. Assuming the acceleration is -9.8 m/s² (a), we can calculate the initial velocity of the skateboarder (v₀) using the kinematic equation A.

$v = v_o + a \Delta t\\\\v_o = v - a \Delta t = (-4.5 m/s) - (-9.8 m/s^{2} ) \times 3 s = 24.9 m/s$

Given the time, the final velocity and the acceleration, we can calculate the initial velocity using the kinematic equation A:

$v = v_o + a \Delta t$

You can comfortably hold your fingers close beside a candle flame, but not very close above the flame. why? challenge (optional)

Inessa05 [86]

The candle flame releases hot gases, which directly go in upwards directions. Due to which the air near the flame of the candle is very hot and dense. The particles along with vapour move up. And since the sideways, the air is not very dense and hot, we are able to hold the candle. In anti-gravity region, there will be no density differences and also, the convection process wont occur. So, the candle quickly snuffs off.
