In what way is the planet Uranus unique

1 answer:

6 0

It is unique for many many ways:
1.)Unlike the other planets of the solar system, Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star. This unusual orientation might be due to a collision with a planet-size body, or several small bodies, soon after it was formed

Calculate the Ka for the following acid. Determine if it is a strong or weak acid. HClO2(aq) dissolves in aqueous solution to fo

Talja [164]

Answer:

The value of Ka $= 1.1*10^{-2}$

It is a weak acid

Explanation:

From the question we are told that

The concentration of $[HClO_2]=0.24M$

The concentration of $[H^+]=0.051M$

The concentration of $[ClO_2^-]=0.051M$

Generally the equation for the ionic dissociation of $HClO_2$ is

$HClO_2_(aq) -------> H^{+}_{(aq)} + ClO_2^{-}_{(aq)}$

The equilibrium constant is mathematically represented as

$Ka = \frac{concentration \ of \ product }{concentration \ of \ reactant }$

$= \frac{[H^+][ClO_2^-]}{[HClO_2]}$

Substituting values since all value of concentration are at equilibrium

$Ka = \frac{0.051 * 0.051}{0.24}$

$= 1.1*10^{-2}$

Since the value of is less than 1 it show that in water it dose not completely

disassociated so it an acid that is weak

What causes the surface ocean currents in the Northern Hemisphere to deflect to the right, and the currents in the Southern Hemi

AVprozaik [17]

The Coriolis force is an inertial force that acts on objects that are in motion relative to a rotation reference frame. This causes moving objects to the right ( with respect to the direction of travel ) in the Northern hemisphere and to the left in the Southern hemisphere. The horizontal deflection is zero at the equator. It also causes the surface ocean currents in the Northern hemisphere to deflect to the right and the currents in the Southern hemisphere to deflect to the left.
Answer: the Coriolis force.

BRAINLIESTTT ASAP!! PLEASE HELP ME :)

Ratling [72]

Jot down the formula of the ionic compound. Let's say the ionic compound you're working with is NaCl.

Write the name of the metal.

Add the name of the non-metal with an –ide ending.

Combine the cation and anion names.

Practice naming more simple ionic compounds.

1. We have new knowledge of how charge can be transferred from one object to another

NeX [460]

Charge can be transferred from one object to another in three way conduction, polarization, and friction

Whenever electrons are transferred between objects, neutral matter becomes charged and three ways this can occur are referred to as conduction, polarization, and friction conduction means when there is direct contact between materials that differ in their ability to give up or accept electrons when two different materials are rubbed together, there is a transfer of electrons from one material to the other material and this causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer)

Here given object is water + balloon; balloon + wall; tape then you rub a balloon against your clothes and it sticks to the wall, you are adding a surplus of electrons (negative charges) to the surface of the balloon the wall is now more positively charged than the balloon and we tested the conductivity of deionized water positively charged

Know more about charge transferred one object to another

What is relative isotopic mass

lidiya [134]

Answer:

Relative atomic mass or atomic weight is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant. The atomic mass constant is defined as being 1/12 of the mass of a carbon-12 atom.
