Answer:
1045
Answer: 1045 J of energy was released on cooling the down the water from 20 °C to 10 °C.
Answer:
Sodium - malleable, soft, and shiny
Silicon - has properties of both metals and nonmetals
Bromine - highly reactive gas
Argon - non-reactive gas
Explanation:
Sodium is an alkaline metal. Just like other alkaline metals, it's malleable, soft, and shiny.
Silicon is a metalloid. Metalloids are elements that have properties of both metals and nonmetals.
Bromine a highly reactive chemical element. It is a fuming red-brown liquid at room temperature that evaporates to form a similarly coloured gas.
Argon is a noble gas. Just like other noble gases, it's non-reactive.
The number is 25. The square root of 25 is 5 and 5x2 is 10 and then 10+5 is 15

Answer:</h3>
#1. Balanced equation: 2C₅H₅ + Fe → Fe(C₅H₅)₂
#2. Type of reaction: Synthesis reaction
<h3>
Explanation:</h3>
- Balanced equations are equations that obey the law of conservation of mass.
- When an equation is balanced the number of atoms of each element is equal on both side of the equation.
- Equations are balanced by putting appropriate coefficients on the reactants and products.
- In our case, we are going to put coefficients 2, 1 and 1.
- Thus, the balanced equation will be;
2C₅H₅ + Fe → Fe(C₅H₅)₂
- This type of a reaction is known as synthesis reaction, in which two or more reactants or compounds combine to form a single compound or product.
