Which of the following statements about block-based coding is false?



- Block-based programs use characters, which are called sprites.


- Each block of code corresponds to at least one code instruction.


- Block-based coding involves dragging and dropping blocks onto an editor.


- You need to understand the coding language behind the blocks in order to successfully build a block-based program

Answers

Answer:

Im pretty sure the answer to your question is A.

Explanation:

all others make sense.

Answer: You need to understand the coding language behind the blocks in order to successfully build a block-based program.

Explanation: Block based coding is mostly just drag-and-drop. If you go to a place like Scratch, you'll see that they have entire games made completely out of blocks. I've made a few decently complicated programs there, and none of them require me to know the coding language behind the blocks.

Which of the following is an example of a syntax error in a program?



- A program is supposed to calculate the sum of three numbers, but displays the wrong answer.


- The programmer typed “nmae” instead of “name” when using a variable.


- A sprite in a block-based program won’t move backwards, only forwards.


- The music stops playing halfway through the program instead of continuing until the end.

Answers

Answer: The programer typed “nmae” instead of “name” when using a variable
Explanation: a syntax error is an error in the syntax of a sequence of characters or tokens that is intended to be written in a particular programming language. For compiled languages, syntax errors are detected at compile-time. A program will not compile until all syntax errors are corrected. the message “nmae” would be undeliverable because of a syntax error. Poorly or incorrectly formatted information might be entered by a programmer, end user, or even by computer software itself.
The second one because it is miss spelling something specific which leads to this type of error

How does the formation of an ionic bond differ from the formation of a covalent bond?1) An ionic bond is where one atom transfers at least one electron from another atom in an attempt to fill its electron shell. A covalent bond is when electrons are shared between atoms and there is equality between atoms in relation to their electrons.2) Ionic bonds form by the transfer of electrons. Covalent bonds form by sharing electrons. In ionic bonding, electrons are completely transferred from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. Ions that have a positive charge are called cations and the ones that have a negative charge are called anions. On the other hand, covalent bonds can be formed by any equal or unequal sharing of electrons. The substances formed by ionic bonds are called compounds and those formed by covalent bonds are referred to as molecules.3) The formation of an ionic bond differs from the formation of a covalent bond by being so, a covalent bond forms when one electron in the outer electron orbit of each atom is shared between the two atoms. Covalent has only one electron to be shared and ionic has more than one electron to be transferred. (HELP IS NEEDED SOON.
