In an exothermic reaction, chemical energy is converted to _____.
1.thermal
2. mechanical
The chemical reactions are generally of many types. The exothermic and endothermic reactions are important among them. In an exothermic reaction the chemical energy is converted to thermal energy. The correct option is 1.
What is exothermic reaction?The chemical reactions which proceed with the evolution of heat energy are defined as the exothermic reactions. The chemical reactions which proceed with the absorption of heat energy are called endothermic reactions.
In an exothermic reaction, system loses heat to surroundings. Since heat is given out in exothermic reactions, the enthalpy of the products will be less than that of the reactants.
In exothermic reaction, q will be negative and the enthalpy change will be also negative. In this reaction chemical bonds are broken and new bonds are formed. The chemical energy is converted to kinetic energy which is released as heat.
Thus exothermic reaction releases thermal energy.

Ask me whats mangles gender. I will give yuh answer (Mangle is from fnaf)
The Phone Guy refers to Mangle as "he/him," yet Mangle also appeared in the Custom Night setting known as "Ladies Night." Scott Cawthon finally said, "Yes," when asked about Mangle's gender.
Who is mangles?They have been addressed using the pronouns "he," "he," and "her." Bonnie is regarded by Scott as the most frightful animatronic.
While creating Five Nights at Freddy's, he frequently had nightmares about Bonnie, and while creating Bonnie's artificial intelligence, he even unintentionally caused himself jump scares.
According to one explanation, it is based on Mangle from the Five Nights at Freddy's video game series and is a jumbled mass of different genders with a charming horror style. This definition fits under the category of aesthetic gender.
Therefore, Scott Cawthon finally said, "Yes," when asked about Mangle's gender.

I need yall help with this one and i can make yall brilientist if u get it right plus yall get 50 points

C. and B. im pretty sure hope it helps
Explanation:
I NEED HELP ASAP PLZZZZZ!!!
Answer:
[tex]\boxed {\boxed {\sf Choice \ B }}[/tex]
Explanation:
First, let's think about what a greenhouse is. It's a building made of glass that plants grow in. The glass traps heat, so the plants can continue to grow, even in the cold and harsh winter months.
The Greenhouse Effect is like that, but on a much greater scale.: planet Earth! Gas particles, infamously carbon dioxide and methane, trap the heat. The sun heats up our planet during the day and it cools at night. The heat goes back into space, but some is trapped by the gases.
This is why many scientists are concerned about global warming. They worry that burning fossil fuels releases carbon dioxide, which traps heat and warm the planet.
So, based on what we learned about the greenhouse effect, choice B is correct.

How does this evidence help explain why the skin cancer rate is higher in Australia than in Brazil, even though the two countries get the same amount of sunlight?
Answer:
The Ozone layer
Explanation:
Ozone in the atmosphere can absorb ultraviolet light, which stops the light from reaching Earth’s surface, so people absorb less of it. Australia has less ozone than other places, like Brazil, and this is why Australia gets more ultraviolet light.

Use the drop-down menus to select the names of the labeled structures.
A: B: C:
Answer:
A: petal
B:stigma
c: stamen
Explanation:
A flower is considered as a complete one if it has petals, stamen, carpel and sepals. Sometimes pistil is present. Here in the structure part A is Petal, B is Stigma and C is stamen.
What are parts of a flower?The calyx, corolla, androecium, and gynoecium are found to be the four whorls of a modified leaves which constitute the flower. One of the flower parts in each of the whorl contains sepals, petals, stamens and pistils.
Here A is petal. This part is the bright coloured region which attracts bees and birds. This part help us to differentiate one flower from another. Some petals are dark coloured whereas some other are pale coloured.
Here B is stigma. The stigma is the sticky part of a flower. It is the specially adapted portion of the pistil modified for the reception of pollen. It has a feathery, branched elongated structure.
Here C is stamen - The male reproductive part of a flower is called the stamen. The stamen has long slender stalk called the filament with a two -lobed anther at the tip.
Thus the given parts are petal, stigma and stamen.
