Answer:
RbH(s)+ H2O(l) → RbOH + H2
Explanation:
The reaction is;
RbH(s)+ H2O(l) → Product
From Ahmad's statement, we know that the product of he reaction is going to be an Hydroxide (-OH) and hydrogen gas (H2)
So we have;
RbH(s)+ H2O(l) → RbOH + H2
Answer:
+3
Explanation:
The name of this compound would be nickel (III) oxide. Oxygen typically has a charge of -2. Given there are 3 oxygen atoms, that would equal a charge of -6. The nickel is the cation and must equal the charge of the anion, so must have a charge of +6. Since there are 2 nickel atoms, the charge on each must be +3.
Answer:
When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.Although planets surround stars in the galaxy, how they form remains a subject of debate. Despite the wealth of worlds in our own solar system, scientists still aren't certain how planets are built. Currently, two theories are duking it out for the role of champion. The first and most widely accepted theory, core accretion, works well with the formation of the terrestrial planets like Earth but has problems with giant planets. The second, the disk instability method, may account for the creation of these giant planets. Scientists are continuing to study planets in and out of the solar system in an effort to better understand which of these methods is most accurate.

Answer:
False.
Explanation:
The chemical hazard label with colors indicates the specific class of hazard. Hazardous Materials Identification System is defined as the numerical hazard rating then incorporate the use of labels with colors.
Blue color: This sign conveys the health hazards of the material, means that long-term exposure to the material can cause the problems, for example kidney damage, and emphysema.
Red for color: This sign conveys the flammability hazards of the material.
Yellow for color: This sign conveys the instability hazards of the material.
