Answer:
XCl₂ + 2AgNO₃ —> X(NO₃)₂ + 2AgCl
The coefficients are: 1, 2, 1, 2
Explanation:
XCl₂ + AgNO₃ —> X(NO₃)₂ + AgCl
The equation can be balance as follow:
XCl₂ + AgNO₃ —> X(NO₃)₂ + AgCl
There are 2 atoms of Cl on the left side and 1 atom on the right side. It can be balance by writing 2 before AgCl as shown below:
XCl₂ + AgNO₃ —> X(NO₃)₂ + 2AgCl
There are 2 atoms of Ag on the right side and 1 atom on the left side. It can be balance by writing 2 before AgNO₃ as shown below:
XCl₂ + 2AgNO₃ —> X(NO₃)₂ + 2AgCl
Now, the equation is balanced.
The coefficients are: 1, 2, 1, 2

Does a animal cell have cytolysis?
Answer:
The presence of a cell wall prevents the membrane from bursting,so cytolysis only occurs in animal and protozoa cells which do not have cell walls.
Explanation:
do i have to know the chemical and physical properties of alloys? only chemistry students answer this.
Answer:
yes you do so you know how strong it is how maluble it's is so it can be customised to it's specific use
Answer:
alloy's properties are usually different from those of its component elements. Alloy constituents are usually measured by mass. Unlike pure metals, most alloys do not have a single melting point; rather, they have a melting range in which the substance is a mixture of solid and liquid.
physical properties of alloys:-Alloy steels have a wide range of special properties, such as hardness, toughness, corrosion resistance, magnetizability, and ductility. Nonferrous alloys, mainly copper–nickel, bronze, and aluminum alloys, are much used in coinage.
chemical properties of alloys:-Pure metals are useful but their applications are often limited to each individual metal's properties. Alloys allow metal mixtures that have increased resistance to oxidation, increased strength, conductivity, and melting point; Essentially any property can be manipulated by adjusting alloy concentrations.
dnt learn all thr properties.
these are the main properties..u can learn thse only. hope it will help u
Which statement is true about solids?
Their particles can flow over one another, so they have a fixed volume but no fixed shape.
Their motionless particles are packed together in a fixed arrangement.
Their vibrating particles are packed together in relatively fixed positions.
Their fast-moving particles can expand to take the shape of their container.
Answer:
3
Explanation:
Answer:
Their vibrating particles are packed together in relatively fixed positions.
Explanation:
As you can see in the image below, solid is packed together.
help, please? What science law explains why there should always be the same type of elements on the reactant side as there are on the product side? What does this law state? (HINT: Answer both of these questions. A: The Law of _________________ states that _____________.)
Answer:
the law of conservation of energy states that energy neither created nor destroyed that means in a chemical reaction Mass reactants ( starting material)=tomass of produt
Organisms are classified into different kingdoms based on?...
Answer:
Food and cell type
Explanation:
Kingdoms are by far the most basic legal structure for living objects. Living objects are classified into realms depending on how they consume food, the kinds of cells that produce their bodies, and the total type of tissue in their bodies.
What is needed to change a phase of matter?
The addition or subtraction of thermal energy. For example if you heat up an ice cube, it will melt to become water. If you heat it even more, it will evaporate.
