Answer:
Explanation:
We can use the specific heat formula, which is:
Where <em>q</em> is the energy, <em>m</em> is the mass, <em>c</em> is the specific heat capacity, and ΔT is the change in temperature.
We know the mass is 250 grams. The specific heat capacity of water is 4.18 joules per gram degree Celsius. Let's find the change in temperature.
- ΔT = final temperature - initial temperature
Now we know all the values:
Substitute the known values into the formula.
Multiply the first 2 numbers together. The grams will cancel out.
Multiply again. This time the degrees Celsius will cancel out.
The energy needed is <u>80, 465 Joules.</u>
Is this a answer multiple choice or u just answer it
Answer:
The answer is Relative plenitude alludes to the amount of a specific isotope is available in a given measure of test.
Explanation:
The 'relative plenitude' of an isotope implies the level of that specific isotope that happens in nature. Most components are comprised of a blend of isotopes. The total of the rates of the particular isotopes must indicate 100%. The relative nuclear mass is the weighted normal of the isotopic masses. The percent plenitude of every sort of sweets reveals to you what number of every sort of Aufbau there are in each 100 CANDIES. Percent wealth is additionally relative plenitude. This is only a method for giving us a photo on which kind exists all the more every now and again.
Answer:
NCl₃ + 2 H₂O = HNO₂ + 3 HCl
Explanation:
Let's consider the unbalanced equation showing the reaction between nitrogen trichloride and water to form nitrous acid and hydrochloric acid.
NCl₃ + H₂O = HNO₂ + HCl
We start balancing Cl atoms by multiplying HCl by 3.
NCl₃ + H₂O = HNO₂ + 3 HCl
Then, we balance O atoms by multiplying H₂O by 2.
NCl₃ + 2 H₂O = HNO₂ + 3 HCl
The equation is now balanced.
Fossil fuel is a collective term for buried, combustible deposits or organic materials formed from decayed plants and animals over millions of years ago that had been converted to different substances such as crude oil, coal, natural gas or heavy oils through heat and pressure exposure. They are sometimes known as mineral fuels.
The steps of fossil fuel formation are:
1. The plant uses energy found from its environment to form sugars and carbohydrates.
2. ANIMAL DEATH- for a fossil to form, an animal must die either in water or die out of the water. Water plays a vital role in the fossil formation because it helps in the preservation of the dead organism long enough for it to form.
3. BACTERIAL CONSUMPTION- bacteria eats away the soft parts and leaves the hard part such as the exoskeleton or bones. This hard body parts that are inherently resistant to bacterial erosion are the ones that forms into fossil.
4. SEDIMENTATION- this is the settling of dirt, dust or mud over these remains layer upon layer accumulate through the years
5. PERMINERALIZATION- layers of decomposed plants and animals are buried deep down the earth that they are squelched by the enormous mass of the earth creating intense heat and pressure.
6. After millions of years of heat and pressure, these buried materials transforms into chemicals known as hydrocarbons
7. These so called HYDROCARBONS can either be solid, liquid or gas. The solid form is known as coal. The liquefied form is the petroleum or crude oil. Lastly, the natural gas is the gaseous form.
